6x - 9y=7.5
7y - 2x = -4.5 Answer by drj(1380) (Show Source): You can put this solution on YOUR website! Solve by the elimination method. What is the solution of the system? Simplify your answer.
The following solves the system equations by substitution.
Solve: We'll use substitution. After moving -9*y to the right, we get: , or . Substitute that
into another equation: and simplify: So, we know that y=-0.5. Since , x=0.5.
Answer: .
I hope the above steps were helpful.
