Question

Solve the following equation. 3(2x - 4) = 4(x + 1) x=?

Answer 1

`x=8`

Explanation:

`3\left(2x-4\right)=4\left(x+1\right)`

Expand:

`3* 2x-3* 4=4x+4* 1`

`6x-12=4x+4`

Add 12 to both sides:

`6x-12+12=4x+4+12`

`6x=4x+16`

Subtract 4x from both sides:

`6x-4x=4x+16-4x`

`2x=16`

Divide both sides by 2:

`(2x)/(2)=(16)/(2)`

`x=8`
