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.

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

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   ——

           5

Equation at the end of step

1

:

  48         84

 (—— • x) -  ——  = 0

  10         5

STEP

2

:

           24

Simplify   ——

           5

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

       5      

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
