solve x – y = 1 & 2x + y = 8.... plz answer the question with correct answer mention the method!!!! About the author Valentina
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 Reply

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:
