What is the solution to the equation? 7x + 6 = -22

trapecia [35]

C.) x = -4 is the correct answer

Step-by-step explanation:

In order to solve the equation we have to isolate x on one side of equation

Given

7x + 6 = -22

Subtracting 6 from both sides

$7x+6-6=-22-6\\7x=-28$

Dividing both sides by 7

$\frac{7x}{7}=\frac{-28}{7}\\x=-4$

Hence,

C.) x = -4 is the correct answer
