Answer:
x = -2, y = 6
Explanation:
First, find the opposite of 10 by multiplying 5x+3y=8 by -2 to eliminate 10x.
10x+10y=40
-2(5x+3y=8)
10x+10y=40
-10x-6y=-16 (Subtract 10y - 6y) (Subtract 40 - 16)
4y = 24 (Divide by 4 on both sides)
y = 6
Substitute 6 in the y value in any of the equations.
10x+10(6)=40 (Replaced 10y with 10(6) )
10x+60=40
-60 = -60 (Subtract 60 from both sides)
10x = -20 (Divide by 10 on both sides)
10 10
x = -2
