3.1 Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
24x - (84) 24x - 84
—————————— = ————————

STEP 4:
Pulling out like terms :
4.1 Pull out like factors :
24x - 84 = 12 • (2x - 7)
Equation at the end of step 4:
12 • (2x - 7)
————————————— = 0

The equation now takes the shape :
12 • (2x-7) = 0
Equations which are never true:
5.2 Solve : 12 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
5.3 Solve : 2x-7 = 0
Add 7 to both sides of the equation :
2x = 7
Divide both sides of the equation by 2:
x = 7/2 = 3.500
x = 7/2 = 3.500

Explain how to solve the equation and then check the solution.
9 = q – 4
Sample Response: Use the inverse operation to isolate the variable. Undo the subtraction of 4 by adding 4 to both sides of the equation. –4 + 4 = 0, and 9 + 4 is 13. The solution is q = 13. Check the solution by substituting 13 for q in the original equation, and then simplify. 13 – 4 is 9 and 9 = 9 is a true statement, so 13 is the solution.

Answer:
Use the inverse operation to isolate the variable. Undo the subtraction of 4 by adding 4 to both sides of the equation. –4 + 4 = 0, and 9 + 4 is 13. The solution is q = 13. Check the solution by substituting 13 for q in the original equation, and then simplify. 13 – 4 is 9 and 9 = 9 is a true statement, so 13 is the solution.
Step-by-step explanation:
The solution of the Equation 9 = q – 4 is 13.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
9 = q – 4
We have to use the inverse operation as
Addition inverse Subtraction and vice versa.
Division inverse Multiplication and vice versa.
So, 9 = q – 4
Undo the subtraction of 4 by adding 4 to both sides of the equation.
9 + 4 = q- 4 +4
13 = q
Hence, the solution is 13.

Here’s how you solve questions like these:
First of all, you have to learn the rule on the number line.
if it’s an addition problem, go forward.
if it’s a subtraction problem, go backwards.
if the number is positive, turn to the right.
if the number is negative, turn to the left.
So pretend you’re in between a number line that goes from -10 to 10, or on 0.
< -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 >
Take the first number and look at the rule. Since 2 is positive, you start at that number and face to the right.
< -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 >
>
Next, you take the symbol in between the two numbers. Since it’s the minus sign, or a subtraction problem, you have to get ready to walk backwards But before you do that, check the last number. Since 4 is positive, you still have to face to the right and move 4 spaces backwards.
< -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 >
< < < <

We have to given that;
The expression is,
⇒ (x¹⁴) (x⁻²)³ = xⁿ
So, Solve the expression by rule of exponent for the value of n,
⇒ (x¹⁴) (x⁻²)³ = xⁿ
⇒ (x¹⁴) (x⁻⁶) = xⁿ
⇒ x ¹⁴ ⁺ ⁻⁶ = xⁿ
⇒ x ¹⁴⁻⁶ = xⁿ
⇒ x⁸ = xⁿ
By comparing, we get;
⇒ n = 8
