Question

For each problem given, circle correct or not correct. If it is not correct, state what is incorrect and write the correct solution.

Answer 1

x = -4

Explanation:

The second line contains an error.

-2(x - 5) = -2x + 10; the second line has -2x - 10.

Correct solution:

-2x + 10 - 6 = 12

-2x + 4 = 12

-2x = 8

x = -4
