Question

3x+7=x - 15 i dont know how to solve it
the answer is -11 but i dont know how to get to that

Answer 1

3x + 7 = x - 15

First, make sure to subtract
`x` from both sides.

`3x + 7 - x = -15`
Second, simplify 3x - x to get 2x, and then keep the 7.

`2x + 7 = -15`
Third, subtract
`7` from both sides.

`2x = -15 - 7`
Fourth, simplify -15 - 7 to get -22.

`2x = -22`
Fifth, take the 2 and divide both sides by it, keeping the
`x` by itself.

`x = - (22)/(2)`
Sixth, since 11 goes into 2 to get 22, simplify the fraction to 11.

`x = -11`

Answer: x = -11
