    I will try to help, but it may take me a bit of time to remember. This wasn't my favorite topic in algebra, but I will try my best.

    x = −13 and x = −3 x = 3 and x = −3 x = 3 and x = 13 No solution

    Every absolute equation has 2 solutions.

    Divide both sides by 3 −3|x + 7| /3= −12/3 |x+7|=4 We know either x+7=4or x+7=−4

    x+7=4(Possibility 1) x+7=−4(Possibility 2) Solve both for x this one does have 2 solutions

    For possibility 1, x + 7 = 4 -7 - 7 x = -3

    So it's the first one becuase x+7+-4 is -13

    There are 2 solutions for each absolute value equation. Unless one doesn't have a solution, both are correct.
