Question

By solving a pair of linear equations x+y=8 and 2y - x=1, the values of 'x' and
'y'are
A. x = 3, y = 5
B.x = 4, y = 4
C. x = 5, y = 3
D. x=-5, y = -3​

Answer 1

Answer:

(C) x = 5 , y = 3

Step-by-step explanation:

x + y = 8 ..........(i)

2y - x = 1.........(ii)

Adding equation (i) and equation (ii)

x + y + 2y - x = 8 + 1

3y = 9

y = 9/3

y = 3

Putting value of y in equation (i)

x + 3 = 8

x = 5

∴ x = 5 , y = 3

Option C is correct.
