Answer 1

Simplifique

2x + -3 = 12 + -1x

Reorder the terms:

-3 + 2x = 12 + -1x

Solving

-3 + 2x = 12 + -1x

Solving for variable 'x'.

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

Add 'x' to each side of the equation.

-3 + 2x + x = 12 + -1x + x

Combine like terms: 2x + x = 3x

-3 + 3x = 12 + -1x + x

Combine like terms: -1x + x = 0

-3 + 3x = 12 + 0

-3 + 3x = 12

Add '3' to each side of the equation.

-3 + 3 + 3x = 12 + 3

Combine like terms: -3 + 3 = 0

0 + 3x = 12 + 3

3x = 12 + 3

Combine like terms: 12 + 3 = 15

3x = 15

Divide each side by '3'.

x = 5

Simplifying

x = 5
