here is your answer

7x - 15y = 2  \\  x =  \frac{2 + 15y}{7} ..........(1)

by substituting the value of x in another equation ,we get

( \frac{2 + 15y}{7} ) + 2y = 3 \\  =  > 2 + 15y + 14y = 21 \\  =  > y =  \frac{19}{29}

similarly by puting the value of y in (1)

we get

x =  \frac{2 + 15 \frac{19}{29} }{7 }  \\  \\  =  > x =  \frac{2053}{7}

7x-15y=2

x=(2+15y)/7----- (1)

now,

x+2y=3

(2+15y)/7+2y=3

(2+15y+14y)/7=3

2+29y=21

29y=21-2

y=19/29

then,x=(2+15(19/29))÷7
