Answer:

x = -3

Step-by-step explanation:

Simplifying

-7x + 6 = 27

Reorder the terms:

6 + -7x = 27

Solving

6 + -7x = 27

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6' to each side of the equation.

6 + -6 + -7x = 27 + -6

Combine like terms: 6 + -6 = 0

0 + -7x = 27 + -6

-7x = 27 + -6

Combine like terms: 27 + -6 = 21

-7x = 21

Divide each side by '-7'.

x = -3

Simplifying

x = -3
