Answer 1

Answer

Step-by-step explanation:

let the no. of pants be x and no. of skirts be y

1st case

A/C

2x-2=y or

2x-y-2=0____1

-y-2=-2x

-y=-2x+2

y=2x-2____2

2nd case

A/C

3x-4=y

3x-y-4=0

putting the value of equation 2

3x-(2x-2)-4=0

3x-2x+2-4=0

x-2=0

x=2

from equation 2

y=2x-2

=2×2-2

=4-2

=2

so there are 2 pants and 2 skirts

hope it would be helpful✌
