Question

2x+8y=19and 2x+11y=28

Answer 1

Answer:

subtract 1 and 2

8y-11y=19-28

-3y=-9

y=3

put the value of y in equation 1

2x+8y=19

2x+8×3=19

2x+24=19

2x=19-24

2x=-5

x=-5/2

Answer 2

Step-by-step explanation:

2x+8y=19

2x+y=19/8

x+y=19/8*1/2

x+y=19/16

2x+11y=28

2x+y=28/11

x+y=28/11*1/2

x+y=28/2

x+y=14
