Answer 2

brainliest please

Step-by-step explanation:

pens is x

and pencils is y

by first condition

7x+2y=22..........(1)

by second condition

3x+4y=11...........(2)

equ (1) * 2 == 14x +4y=44.........(3)

equ. (2) - equ. (3)

3x+4y=11

-14x-4y=-44

___________

-11x = -33

x = -33/-11

x=3

by putting x=3 in equ. (1)

7x+2y=22

7*3+2y=22

21+2y=22

2y=22-21

y=1/2

x=pens = 3

y= pencils =1/2
