Question 417980
x + 2y = -1
3x - 2y = 9
------------
4x = 8 {added the two equations together}
x = 2 {divided both sides by 4}


x + 2y = -1 {top equation}
2 + 2y = -1 {substituted 2, in for x, into top equation}
2y = -3 {subtracted 2 from both sides}
y = -3/2 {divided both sides by 2}


x = 2 and y = -3/2
