-10x +8y=-44
4x+8y=40
Solve for X and Y!!
you can subtract the two equations, like so:
4x+8y-(-10x+8y) = 40-(-44)
simplifying:
4x+8y+10x-8y = 40+44
14x = 84
x = 6
4(6)+8y = 40
24+8y = 40
8y = 40 - 24
8y = 16
y = 2
hope this helped! please correct me if i am wrong:)
First, let's subtract these two equations
If we do that we get:
-14x=-84
divide both sides by -14
x=6
We can now plug in x=6 in either of the two equations. I'll plug it into the second one
4(6) + 8y = 40
24+8y=40
-24 -24
8y= 16
