Answer 2

Answer:

x = 4

Step-by-step explanation:

Simplifying

3x + -2 = 18 + -2x

Reorder the terms:

-2 + 3x = 18 + -2x

Solving

-2 + 3x = 18 + -2x

Solving for variable 'x'.

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

Add '2x' to each side of the equation.

-2 + 3x + 2x = 18 + -2x + 2x

Combine like terms: 3x + 2x = 5x

-2 + 5x = 18 + -2x + 2x

Combine like terms: -2x + 2x = 0

-2 + 5x = 18 + 0

-2 + 5x = 18

Add '2' to each side of the equation.

-2 + 2 + 5x = 18 + 2

Combine like terms: -2 + 2 = 0

0 + 5x = 18 + 2

5x = 18 + 2

Combine like terms: 18 + 2 = 20

5x = 20

Divide each side by '5'.

x = 4

Simplifying

x = 4
