Solve by elimination x-7y=62, -x +6y=42
Answer by ankor@dixie-net.com(22740)   (Show Source):
You can put this solution on YOUR website! Solve by elimination
x - 7y = 62,
-x + 6y = 42
-------------------adding eliminates x, find y
-y = 104
y has to be positive, multiply both sides by -1
y = -104
:
Find x using the 1st equation, replace y with -104
x - 7(-104) = 62
x + 728 = 62
x = 62 - 728
x = -666
:
:
Check solution in the 2nd equation, replace x and y
-(-666) + 6(-104) = 42
666 - 624 = 42, confirms our solutions of x=-666 and y=-104
