Question 938238: Using the method of substitution to help solve for this equation.
x+3y=1
-2x+2y=6
I am stuck this is what I have so far
x+3(-2x+6)=1
x-6+24=1
Am I on the right track?
Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! First solve -2x+2y=6 for y.
-2x+2y=6
2y=6+2x
2y = 2x+6
y = x+3 ... divide every term by 2
-------------------------------------------------------
Now turn to x+3y=1
x+3y=1
x+3(x+3)=1 ... plug in y = x+3
x+3x+9 = 1
4x+9 = 1
4x = 1-9
4x = -8
I'll let you finish solving for x. Once you have the value of x, use it in y = x+3 to find y.
