Question 222382: Solve by the substitution method.
6x+7y=-29
x=3-9y
What is the solution of the system? Type an ordered pair. Answer by drj(1380) (Show Source):
Solve: We'll use substitution. After moving 7*y to the right, we get: , or . Substitute that
into another equation: and simplify: So, we know that y=1. Since , x=-6.
Answer: .
I hope the above steps were helpful.
