Question

For the parallelogram, find the value of the variables. Show your work

Answer 1

The opposite sides on a parallelogram have equal side lengths. Assuming that your drawing is supposed to contain those expressions and values on opposite sides, 5x + 2 is opposite of 17, and 3y - 6 is opposite of 21, so we equate them:
5x + 2 = 17
x = 3
Similarly, 3y - 6 = 21
y = 9
