2x - y = 4 --------------- eq1
3x - 2y = 5 -------------- eq2
Elimination method -- make the coefficient of any one variable equal (whether it's x or y)
Let us take 'y'
2x - y = 4 ------- x 2
3x - 2y = 5 ------- x 1
So, now new equations
4x - 2y = 8
3x - 2y = 5
(-) (+) (-)
-----------------------
x = 3
we got x = 3
put the value of 'x' in any one of the above equation
4x - 2y = 8
4(3) - 2y = 8
-2y = -12 + 8
-2y = -4
y = 2
