Question

-15 + 12x = 5x + 7 -3x
SOLVE FOR X

Answer 1

Answer:
`x=(11)/(5)`

Simplify both sides of the equation

`-15+12x=5x+7+-3x`

`12x-15=(5x+-3x)+(7)` (Combine Like Terms)

`12x-15=2x+7`

Subtract 2x from both sides

`12x-15-2x=2x+7-2x\\10x-15=7`

Divide both sides by 10

`(10x)/(10) =(22)/(10)`

`x=(11)/(5)`

Answer 2

`x = 2.2`

Explanation:

`- 15 + 12x = 5x + 7 - 3x \\ + 12x - 5x + 3x = 15 + 7 \\ 10x = 22 \\ (10x)/(10) = (22)/(10) \\ x = 2.2`
