Solve 11x-6y=3 ; 5x-8y=-25

Fiesta28 [93]

Answer: x=3 and y=5

Step-by-step explanation: 11x-6y=3, 5x-8y=-25

11x-6y+6y=3+6y

11x/11=3/11+6y/11

x=3+6y/11

5(3+6y/11)-8y(11)/11

5(6y+3)-88y/11

30y+15-88y/11

88y-30y

58y

11(15-58y)/11=11(-25)

15-58y-15=-275-15

-58y/-58=-290/-58

y=5

x=3+6(5)/11

3+30

33/11

x=3

x=3, y=5
