You can put this solution on YOUR website!
1. x%2B9y=53
2.2x%2B9y=52
Use equation 1 to solve for x.
1. x%2B9y=53
x=53-9y
Now substitute this value into equation 2.
2.2x%2B9y=52
2%2853-9y%29%2B9y=52
106-18y%2B9y=52
-9y=-54
y=6
Now go back and solve for x.
x=53-9y
x=53-9%286%29
x=53-54
x=-1
The solution is x=-1 and y=6.
