    In a rhombus, each diagonal bisects a pair of opposite angles.

    I keep getting 6 at the very end, is that correct?

    No, x is not 6. How did you set up your equation?

    I'm doing what my teacher says, solve both equations for x then adding them together. I did just redo it the way he told me to and i got 5

    2x + 4=2 + 5x-8=3 then 3+2=5 This is what my teacher taught me but it just doesnt seem right

    Since the diagonal bisects the opposite angles, that means m<ACD = m<ACB, which means: 2x + 4 = 5x - 8 This is the equation you must solve.

    Thanks. I hope you understood the problem. You need to take the understanding of the geometry part to then handle the algebra part
