2x - 3y = 3 ------ Eq.1 multiply this by -5
5x - 4y = 4 ------ Eq.2 multiply rhis by 2
_____________________________________ the result after multiply both equation
-5 ( 2x - 3y = 3 )
2 ( 5x - 4y = 4 )
_________________
-10x + 15y = -15
10x - 8y = 8
_________________ by using the elimination method the result will be
7y = -7
y = -7/7 ,,,,,,,,,,, Y = -1
to find the value of X, put the value of Y in Eq.1 :
2x - 3y = 3
2x - 3(-1) = 3
2x + 3 = 3
2x = zero ,,,,,,,,,,, X = Zero
