solve the sytem of equation by substituition.

11x+2y=76 ; 7y-6x= -1

11x + 2y = 76

2y = 76- 11x

y = (76 - 11x) / 2 (3)

putting value of y in equation

7y - 6x = -1

7(76-11x)/2 - 6x = -1

(532 - 77x)/2 - 6x = -1

532 - 77x- 12x = -2

-89x = -534

x = -534/ - 89

x = 6

putting the value of x in equation (3) we get-

y = 5
