18 is the answer you're welcome
9.
2x+3+x+9 = 180 => 3x = 168 => x = 56;
m(<ABD) = 2*56 + 3 = 115.
First you condense the right side (4x+8=4x-13)
We know this problem has no solution because if you subtract 4x from each side you will get 8=-13 and that is impossible.
Therefore there are no solutions
