    Add the like terms. And you are not solving it. You are simplifying.

    2y + 7 = -1 (it was your original problem) 2y = -1 - 7 2y = -8 y = -4

    1) Your ultimate goal is to bring all the constants onto one side of the equal sign Therefore, lets move the + 7 to the other side by substracting 7 with -1, resulting -8

    Now your left with 2y = -8 Divide by 2 to get "y" by itself y = -8/2 y = -4 is your answer when simplified
