can u show me full steps?
OpenStudy (anonymous):
This is a system of equations: If you multiply the second equation by -3 and add the equations together, y will cancel out. 5x - 3y = 47 -18x + 3y = -21 Now you have -13x = 26 So x = -2 Now plug in x into equation 1: 5(-2) - 3y = 47 -10 - 3y = 47 -3y = 57 y = -57/3 If this helps, please choose good answer.
