Solve for x. 8 - 3x - x += 12 (a) -1 (b) -2 (c) -5 (d) -10

Simplifying

8 + -3x + -1x = 12

Combine like terms: -3x + -1x = -4x

8 + -4x = 12

Solving

8 + -4x = 12

Solving for variable 'x'.

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

Add '-8' to each side of the equation.

8 + -8 + -4x = 12 + -8

Combine like terms: 8 + -8 = 0

0 + -4x = 12 + -8

-4x = 12 + -8

Combine like terms: 12 + -8 = 4

-4x = 4

Divide each side by '-4'.

x = -1

Simplifying

x = -1
