Question

x-y=1 and 2x+y=8 by elimination method​

Answer 1

Answer:

ELIMINATION METHOD

→x-y=1__(1)

→2x+y=8_(2)

multiply eq 1 ×(2) and eq 2×(1)

→2x-2y=2

→2x+y=8

➡️ 2x-2y=2

➡️ 2x+y=8

(-) (-) (-)

_________

0 -3y=-6

y=-6/-3

y=2

substitute y=2 in equation no (2)

➡️2x+y=8

➡️2x+2=8

➡️2x=8-2

➡️2x=6

➡️x=3

➡️x=3 and y=2
