Question

In the pair of linear equations x+y=9 and x-y=1, the value of x and y are a) 5 and 4 b) 4 and 5 c) 6 and 3 d) 3 and 6

Answer 1

Answer:

Answer(a) x=5,y=4

Step-by-step explanation:

Answer 2

The value of x and y is 5 and 4 respectively.

Step-by-step explanation:

Given,

x + y = 9....................(i)

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

Add equation (i) and (ii),

x + y + x - y = 9 + 1

=> 2x = 10

=> x = $\frac{10}{2}$ = 5

Plug the value of x in equation(i),

5 + y = 9

=> y = 9 - 5 = 4.

Hence, the value of x and y is 5 and 4 respectively.
