To solve this system of linear equations , either simply multiply a value to get the x and y terms equal, and then add them up, and if there are - and + signs it will cancel out.
2 ( X - y ) = 4
2x - 2y = 8
X + 2y = 4
3x = 12
X = 4.
2y + 4 = 4
2y = 0
Y = 0.
(4,0). This is the solution that matches both linear equations.
