Answer 2

Step-by-step explanation:

xy-x(y-3)+3(y-3)=18

xy-xy-3x+3y-9=18

-3x+3y-9=18

-3x+3y=18+9

-3x+3y=27_____1

x(y+3)+3(y+3)-xy=60

xy+3x+3y+9-xy=60

3x+3y=60-9

-3x+3y=51____2

Now, substract 2 from 1

3x+3y=51

-3x+3y=27

9y=24

y=24/9

y=8/3

substitute y in eq. 2

3x+3y=51

3x+3(8/3)=51

3x+8=51

3x=51-8

3x=43

x=43/3

HOPE THIS IS HELPFUL TO YOU
