ANSWER
(1). [tex]2(x - 4) = 56[/tex]
We expand bracket to get,
(2). [tex]2x - 8 = 56[/tex]
Next, we add the additive inverse of -8, which is 8 to both sides of the equation to get,
(3). Error:
[tex]2x - 8 + 8 = 56 - 8[/tex]
This is where the error occurred. Instead of adding 8 on the right hand side, 8 was rather subtracted.
Expected equation:
[tex]2x - 8 + 8 = 56 + 8[/tex]
(4). Error:
[tex]2x = 48[/tex]
Expected equation:
[tex]2x = 64[/tex]
(5). Error:
[tex] \frac{2x}{2} = \frac{48}{2} [/tex]
Expected equation:
[tex] \frac{2x}{2} = \frac{64}{2} [/tex]
(6). Error:
[tex]x = 24[/tex]
Expected answer:
[tex]x = 32[/tex]
