X+2y=8
2x-y=1
mathe question

x = 2 and y = 3

Step-by-step explanation:

We have

x+2y = 8 equation (i)

2x-y = 1 equation (ii)

Now,

x+2y = 8

or, x = 8-2y equation (iii)

Again,

2x-y = 1

or, 2x = 1+y

or, 2x-1 = y

Putting the value of 'x' from equation (iii)

or, 2(8-2y)-1 = y

or, 16-4y-1 = y

or, 16-1 = y+4y

or, 15 = 5y

or, y = 15/5

or, y = 3

Putting the value of 'y' in equation (iii)

x = 8-2y

or, x = 8-(2×3)

or, x = 8-6

or, x = 2

Therefore, x = 2 and y = 3.
