How do you solve the following system?: #5x +5y =27, 9x -5y = 0#
We have two equations,
Now looking at the equation we need to substitute in for, it would be easier for us to plug something in with a denominator of 5 so they would cancel out and we can do a little less math. So we shall solve for y in this equation.
Now we plug this y into the other equation.
Now we plug this into the other equation.
My calculator isn't working right now so I can't quite give you decimal values but those fractions should be correct.
