Question

-15x + 5 = -10x + 25 solve for x

Answer 1

`15x + 5 = -10x + 25`

`15x+5-5=-10x+25-5`

`15x=-10x+20`

`15x+10x=-10x+20+10x`

`25x=20`

`(25x)/(25)=(20)/(25)`

`x=(4)/(5)`

Answer 2

Move all terms containing x to the left side of the equation.

−5x+5=25

Move all terms not containing x to the right side of the equation.

−5x=20
