Step-by-step explanation:

grammer

Answer 2

11x-9y=-4 ____ 1.

6x-5y=-3 ____2.

let eqn. 2. became

6x-5y=-3

6x=-3+5y

6x=5y-3

x=5y-3/6

Now putting the value 'x' in 1.

11x-9y=-4

x=5y-3/6

11(5y-3/6)-9y=-4

55y-33/6-9y=-4

55y-33-54y=-24

y-33=-24

y=-24+33

y=9

putting the value 'y' in eqn. 2.

6x-5y=-3

y=9

6x-5(9)=-3

6x-45=-3

6x=-3+45

6x=45-3

6x=42

x=42/6

x=7

y=9

x=7
