Hope that helps. If you have any doubts plz let me know.

Answer 2

56-x=728+2x

1.) rearrange

`56x = 728 + 2x \\ \ - x + 56 = 728 + 2x`

`- x + 56 = 728 + 2 x \\ \\ - x + 56 = 2x + 728`

2.)subtract 56 on both side

`- x + 56 = 2x + 728 \\ \ - x + 56 - 56 = 2x + 728 - 56`

3.) simplify

`- x = 2x + 672`

4.)Subtract 2 on both sides

`- x = 2x + 672 \\ \\ - x - 2x = 2x + 672 - 2x`

5.) simplify

`- x - 2x = 2x + 672 - 2x \\ \\ - 3x = 2x + 672 - 2x \\ \\ - 3x = 672`

6.)divide both sides on the same equation

`- 3x = 672 \\ \\ ( - 3x)/( - 3) = (672)/( - 3)`

7.) simplify

`x = - 224`

8.) answer

`x = - 224`
