Question

(iii) Solve : 2x – 3y=9; 2x+y=13.​

Answer 1

Explanation:

2x-3y=9

-2x-y=-13 ( multiply it by -1)

add them

-3y-y=-4

-4y=-4

y=1

x=6

Answer 2

answer:-

2x=9+3y

x=9+3y/2

then putting the value of x in 2nd equation

2x+y=13

2×9+3y/2+y=13

9+3y+y=13

4y=13-9

4y=4

y=4/4

y=1

now in equation 2nd

2x+y=13

now putting y=1

2x+1=13

2x=13-1

2x=12

x=12/2

x=6

hope it helpfull❤️
