Question

Solve by elimination 2x-3y=2 -2x-y=-26

Answer 1

x= 10, y= 6

Explanation:

2x -3y= 2 -----(1)

-2x -y= -26 -----(2)

(1) +(2):

2x -3y -2x -y= 2 -26

-4y= -24

y= -24 ÷(-4)

y= 6

Substitute y= 6 into (1):

2x -3(6)= 2

2x -18= 2

2x= 18 +2

2x= 20

Divide both sides by 2:

x= 20 ÷2

x= 10
