Answer:
x=16, y=-12. (16, -12).
Step-by-step explanation:
5x-16y=272
y=(64-7x)/4
------------------
4y=64-7x
4y+7x=64
5x-16y=272
---------------------
4(4y+7x)=4(64)
5x-16y=272
-----------------
16y+28x=256
5x-16y=272
------------------
33x=528
x=528/33
x=16
5(16)-16y=272
80-16y=272
16y=80-272
16y=-192
y=-192/16
y=-12
