Question

56-x=728+2x what's the answer?

Answer 1

Answer:

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

$- 3x = 672 \\ \\ \frac{ - 3x}{ - 3} = \frac{672}{ - 3}$

7.) simplify

$x = - 224$

8.) answer

$x = - 224$

if u need any help, just let me know

Answer 2

56 - x = 728 + 2x

-x - 2x = 728 - 56
