Question

3x+2y=11
5x-8y=7
Solve it by comparison method

Answer 1

Step-by-step explanation:

3x+2y=11

x=11-2y/3.......(1)

5x-8y=7

x=8y+7/5........(2)

from (1)&(2)

11-2y/3=8y+7/5

55-10y=24y+21

34y=34

y=1

so,

(1) x=11-2.1/3

x=9/3=3

Answer 2

Answer:

15x+10y=55

15x-24y=21

subtraction

34y=34

so,y is 1
