How do you solve the system #7x + 2y = 2# and #6x - 2y = 8#?
I notice that all the terms in the second equation are divisible by 2 and it will be easy to isolate
Divide both sides by 2 to get
Subtract 8 from both sides to get
Now substitute this expression for
Add 8 to both sides to get
Divide both sides by 13 to get
