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.

Answers

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.

Step-by-step explanation:

Divide each term by 4.8 and simplify :) hope this helps, and if it does, can you mark brainiest? my answers have been getting deleted if they are not marked. :(

Answer:

x=3.5

Step-by-step explanation:

Simplify ——

Equation at the end of step

48 84

(—— • x) - —— = 0

10 5

STEP

Simplify ——

Equation at the end of step 2:

24 84

(—— • x) - —— = 0

5 5

STEP 3:

Adding fractions which have a common denominator :

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

—————————— = ————————

5 5

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

For the given expression, the value of n is 8.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

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
