Question #a3b6e

Answer 1

`x = 15`

Explanation:

`-3x+57=x-3`

Take the terms with variable `x` on left hand side of the equation and bring the others on right hand side:

Apply transposition method:

`-3x-x=-3-57`

`-4x = -60`

Dividing both sides by `-4`:

`x = 15`

Answer 2

add 3 to both sides:

`-3x+60=x`

...then add 3x to both sides:

`60 = 4x`

divide each side by 4:

`15 = x`

BAM.

GOOD LUCK!

Answer 3

`x=15`

Explanation:

First we subtract `57` from both sides.
`-3x+57color(blue)-color(blue)57=x-3color(blue)-color(blue)57`
Therefore, `-3x=x-60`.

Subtract `x` from both sides:
#-3xcolor(blue)-color(blue)x=x-60color(blue)-color(blue)x and therefore, #-4x=-60#. Divide both sides by #-4#:

`(-4x)/(-4)=(-60)/(-4)`

Simplify:
`x=15`
