Answer:
Step-by-step explanation:
What we know about this, or should know about this, is that the diagonals bisect each other. That means that
x = y + 2 and y + 10 = 2x - 8
Because the first equation is already solved for x, sub that value into the second equation in place of x to get:
y + 10 = 2(y + 2) - 8 and
y + 10 = 2y + 4 - 8 and
y + 10 = 2y - 4 so
y = 14.
Back sub that in to solve for x:
If x = y + 2 and y = 14, then
x = 16
