Question

5x+
+
2y =_13
7×_5y = _26​

Answer 1

Answer:

5x+2y=-13. (I)

7x-5y=-26. (ii)

5x =-13-2y

x=(-13-2y)/5. (iii)

7x-5y=-26

7x=-26+5y

x=(-26+5y)/7. (iv)

frm iíi n iv we have

(-13-2y)/5 =(-26+5y)/7

7(-13-2y) =5(-26+5y)

-91-14y =-130+25y

-14y-25y=-130+91

-39y=-39

y=1

again putting y=1 in (iii)

x=(-13-2y)/5

=(-13-2×1)/5

=(-13-2)/5

=-15/5

x=-3

hope it helps you friend
