Answer

(8, -24)

Work Step by Step

The two equations are: 1. 4x+y=8 2.-3x-y=0 Lets add the two equations to eliminate the y-terms. We get: x=8 Now lets substitute this value of x into the first equation in order to find the value of y. 4(8)+y=8 32+y=8 (Subtract 32 from both sides) y=-24 So, our solution is (8, -24)
