Question

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

Answer 1

Answer:

$\boxed{x=0}$

Step-by-step 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

Answer:

x=0

Step-by-step 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
