if x = 3

and y = 2

then 2x + y= 8

= 2 x 3 + 2 = 8

= 6 + 2 = 8

and therefore x – y = 1

3 – 2 = 1

Answer:## Question

## ❇️solve x – y = 1 & 2x + y = 8

## Solution ⬇️

## ✍️By substitution method

## ✍️x-y=1..(1)

## ✍️2x+y=8..(2)

_____________

## ️3x=9..(Adding equation 2 and 1)

_____________

[tex] = = > 3x = 9 \\ = = > x = \frac{9}{3} = 3[/tex]

## ✍️x-y=1..(1)

## ✍️3-y=1..(x=3)

## ✍️-y=1-3

## ✍️-y=-2

## ✍️y=2

## ️ (x,y)(3,2) is the solution of the given quadratic equation

Step-by-step explanation:hope you appreciate this ans
