You can put this solution on YOUR website! 4x - y = 3
3x + y = 4
----------
7x = 7 {added the two equations together}
x = 1 {divided both sides by 7}
3x + y = 4 {bottom original equation}
3(1) + y = 4 {substituted 1, in for x, into bottom original equation}
3 + y = 4 {multiplied 3 by 1}
y = 1 {subtracted 3 from both sides}
