You can put this solution on YOUR website!
Look at each set, and think carefully.

#1
Multiply E1 by 3. Multiply E2 by 2.
Add. Find x.
Multiply E1 by 2.
Subtract. Find y.

#2
Multiply E1 by 3. Multiply E2 by 4.
Add. Find x.
Multiply E1 by 2. Multiply E2 by 3.
Subtract. Find y.

#3
You should understand what's going on by now.
Handle this one correctly, and find x=8, y=2.
