Question

Given 28+12x = 8x-4 prove x=8

Answer 1

Answer:
`x=\Large\boxed{-8} \small\text{ instead of 8}`

Explanation:

Given equation

`28+12x=8x-4`

Subtract 8x on both sides

`28+12x-8x=8x-4-8x`

`28+4x=-4`

Subtract 28 on both sides

`28+4x-28=-4-28`

`4x=-32`

Divide 4 on both sides

`4x/4=-32/4`

`x=\Large\boxed{-8}`

Hope this helps!! :)
