Answer:
56-x=728+2x
1.) rearrange
[tex]56x = 728 + 2x \\ \ - x + 56 = 728 + 2x[/tex]
[tex] - x + 56 = 728 + 2 x \\ \\ - x + 56 = 2x + 728[/tex]
2.)subtract 56 on both side
[tex] - x + 56 = 2x + 728 \\ \ - x + 56 - 56 = 2x + 728 - 56[/tex]
3.) simplify
[tex] - x = 2x + 672[/tex]
4.)Subtract 2 on both sides
[tex] - x = 2x + 672 \\ \\ - x - 2x = 2x + 672 - 2x[/tex]
5.) simplify
[tex] - x - 2x = 2x + 672 - 2x \\ \\ - 3x = 2x + 672 - 2x \\ \\ - 3x = 672[/tex]
6.)divide both sides on the same equation
[tex] - 3x = 672 \\ \\ \frac{ - 3x}{ - 3} = \frac{672}{ - 3} [/tex]
7.) simplify
[tex]x = - 224[/tex]
8.) answer
[tex]x = - 224[/tex]
