3x - 4y = 15. ---(1)
5x - 2y = 11-----(2)
multiply equation (1) by 5 and equation (2) by 3
we get ,
15x - 20y = 75
15x - 6 y = 33
____________ by subtracting it !
-14 y = 42
y = -3
now put the value of. " y" in equation (1)
3 x - 4 (-3 ) = 15
3x = 15 - 12
3x = 3
x = 1
hence ,the value of "x " and "y " are 1 and -3.
hope it helps !
thank you !
