Question

8x + 4 = 3 ( x - 1 ) + 7 : solve

Answer 1

`\boxed{x=0}`

Explanation:

`8x+4=3(x-1)+7`

Expand brackets.

`8x+4=3x-3+7`

`8x+4=3x+4`

Subtract both sides by 4.

`8x=3x`

Subtract 3x on both sides.

`8x-3x=0`

`5x=0`

Divide both sides by 5.

`x=0`

Answer 2

x=0

Explanation:

8x + 4 = 3 ( x - 1 ) + 7

Distribute

8x +4 = 3x-3 +7

Combine like terms

8x+4 = 3x +4

Subtract 4 from each side

8x = 3x

Subtract 3x from each side

5x =0

x=0
