2x+3y=92-----------(1)
4x-7y=2--------------(2)
multiple equation (1) with 2
4x+6y=184
4x-7y,=2
--------------------
13y=182 ,y=14
substitute y value in equation 1
2x+3×14=92
2x=92-52
2x=40,x=20
x=20,y=14
(6). 3x+y=142---------(1)
4x-y=138.----------(2)
---------------------
7x=280,x=40
substitute x value in equation 1
