Question 315328: What is the value of the y variable in the solution to the following system of equations?
5x + 4y = 1
4x + 3y = -1
Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!
Multiply the first equation by 4. Multiply the second equation by -5.
Add the two equations term-by-term. The coefficient on the 
variable will go to zero leaving you with a single equation in 
that you can solve by ordinary means.
