Best ResponseYou've already chosen the best response.0I'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

Best ResponseYou've already chosen the best response.02x + 4=2 + 5x8=3 then 3+2=5 This is what my teacher taught me but it just doesnt seem right

Best ResponseYou've already chosen the best response.1Since 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.
