the answer is 5
2
9
2
really all you have to do is multiply 126 * 2 * 7 * 3
then all that's next is to just put the letters in the order they were originally at the end of the answer
B because
Solve for the first variable in one of the equations, then substitute the result into the other equation.
They equal to 180 because they are supplementary angles
