Answer:
BXE equals 158 degrees
Step-by-step explanation:
the 90 degree angle is vertically opposite to angle 32 and a mysterious number.
90+28+40 = 158 = BXE
It should be multiplied by the opposite of the coefficient of y in the first equation, hence
B)) -2
_____
Actually, it depends on your choice of next step. Multiplying by -2 lets you add the two equations. Multiplying by 2 means you need to subtract one equation from the other. We usually find addition easier, so we would usually choose -2, but either can work. It depends on whether you like to add negative numbers or subtract positive ones.
I think the answer is 5x + 6y + 1
