Answer:
y = -8
Step-by-step explanation:
Solve as a system of equations
2x + y = -8 multiply this equation by 2
-4x + 2y = -16 Do not change
Solving: 4x + 2y = -16
<u> -4x +2y = -16 </u>
4y = -32
y = -8
2x + y = -8 Solve for x
2x = -y - 8
x = -y/2 - 8/2
x = -1/2y - 4 Substitute this into your second equation
-4x + 2y = -16
-4(-1/2y - 4) + 2y = -16
2y -16 +2y = -16
4y - 16 = -16
4y = -32
y = -8 x = -1/2(-8) -4 = 4 - 4 = 0
Checking the answer
2(0) + -8 = -8
-4(0) +2(-8) = -1 6 = 0 -16 = -16
4•x-5=3•x+3
Hope this helped you out.
Since you're looking for y, I would rewrite as y= first then plug in the x values and solve.
Y = -2x + 3
y = -2(-1)+3
y=5. (-1,5)
Y=-2(0)+3
y=3
(0,3)
y=-2(1)+3
y=-2+3
y=1
(1,1)
