Answer:
x=-7.88
y=-32.35
the point answer would be (-7.88 , -32.35)
Step-by-step explanation:
First step is to multiply 3x+y=-56 by 4 and you get 12x+4y=-224
Then add each equation together to eliminate y from each equation. You get 17x=-134
Then find divide that equation by 17. You would get x=-7.88
Then plug -7.88 into one of the original equations for x. 5(-7.88)-4y=90 And from that you get -39.4-4y=90
Then isolate the y variable. You would get -4y=129.4
Then divide by -4 and get y=-32.35
