4x-3y=5
Answer by tutorcecilia(2152)   (Show Source):
You can put this solution on YOUR website! -4(x-5y=-3) [Multiply the entire equation by -4 to eliminate the 4x term]
4x-3y=5
__________
.
.
.
-4x + 20y = 12
+4x -3y = 5
_____________
.
.
.
-4x+20y=12 [Add the two equations]
+4x-3y=5
__________
0X+17y=17
.
.
17y=17 [Solve for y]
17y/17=17/17
y=1
.
.
4x-3y=5 [Plug y=1 back into one of the original equations and solve for x]
4x-3(1)=5
4x-3=5
4x-3+3=5-3
4x=2
x=2
.
.
[Check the answers by plugging x=2 and y=1 back into the other original equations]
x-5y=-3
(2)-5(1)=-3
2-5 = -3
-3=-3 [Checks out]
