Question

Ashley simplified the following expression with the given steps 2(x+4)-(2x-8) 2x+4-2x-8 2x-2x+4-8 0-4 -4 Explain to her what her error was and how to correct it

Answer 1

First step, her distributive property was wrong. 2(x + 4) should be 2x + 8.
Since she made a mistake on the first step, all her equation messed up.
2x + 8 - 2x - 8
The correct answer would be 0
