Question 246791: Hi, I have a problem and I need help
The problem is to solve using the substitution method
4x+5y=-2
4y-x=11
I will solve 4y-x=11 which is 4y=x+11
then I dont know what to do

Solve one of the equations for x or y then substitute that in the other.
4y-x=11
4y-11=x
now substitute 4y-11 for x in 4x+5y=-2
4(4y-11)+5y=-2
and solve for y
