Question

Solve using eliminaation method? x+y=8 2x-y=7​

Answer 1

Step-by-step explanation:

x+ y = 8____(1)

& 2x-y = 7_____(2)

so, Multiply 2 in equation 1, we get

2x+2y=16___(3)

Now, on subtracting 2 & 3

2x+2y=16

(2x- y)= 7

-______

3y= 9

y =3

Now put the value of y in equation 1

x+3=8

x=8-3

x=5
