Question

On solving the following pair of linear equations 2x-y=2 and 5x+2y=14 ,then value of x and y are

Answer 1

2x-y=2

5x+2y=14

2x-y=2

2x=2+y

X=2+y/2

5x+2y=14

5(2+y/2)+2y=14

10+5y/2+2y=14

10+5y+4y/2=14

10+9y=14(2)

9y+10=28

9y=28-10

9y=18

y=18/9

y=2

2x-y=2

2x-2=2

2x=2+2

2x=4

X=4/2

X=2

:. X=2

y=2

Answer 2

Answer:

x=2, y=2
