3x+5y=57................(2)

substitute y value in equation(2)

3x+5(x+5)=57

3x+5x+25=57

8x=57-25

8x=32

x=32/8

x=4

substitute x value in equation (1)

y=4+5

y=9

please pick it as best

3x+5(x+5)=57

3x+5x+25=57

8x=57-25

8x=32

x=32/8

**given, y=x+5**

__x=4__

i.e y=4+5

y=9

Therefore, x=4 and y=9
