Sagot :

Answer:

x = 28

Step-by-step explanation:

1) Add 21 to both sides of the equation.

-4x - 21 + 21 = 91 + 21

2) Simplify

A. Add the numbers

-4x = 91 + 21

B. Add the numbers

-4x = 112

3) Divide both sides of the equation by the same term.

-4x/4 = 112/-4

4) Simplify

A. Cancel terms that are in both the numerator and denominator

x = 112/-4

B. Divide the numbers

x = 28
