5х – 4у = 90
3х + y = — 56

how do i solve this using elimination?

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

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
