SOLUTION: 3Y=X+5 3X-9Y= -10

Question 93102: 3Y=X+5 3X-9Y= -10
Answer by tutorcecilia(2152) (Show Source): You can put this solution on YOUR website!
There are several methods for solving this system of equations. I will use the method of addition:
First, line-up the variables:
-x+3y=5
3x-9y=-10
.
.Next, multiply one of the equations by a number that will cause a variable to cancel out:
3(-x+3y=5)=-3x+9y=15
.
.
Add the equations together:
-3x+9y=15
3x-9y=-10
___________
0=-5 (incorrect answer, therefore, there is "no solution"]
