RRB Group D Mock Test - 6 - Question 2

The solution of the equation x-y = 0.9 and 11/2 (x+y)=1 is

Detailed Solution for RRB Group D Mock Test - 6 - Question 2

The given system of equation is
x - y = 0.9 = 9/10 ...(1)
and 11 /2(x + y) = 1
⇒ x + y = 11/2 ...(2)
Adding (1) and (2), we get
2x = 9/10 + 11/2
⇒ 2x = 9 + 55/10 = 64/10
⇒ x = 32/10 = 3.2
When x = 3.2, we get
3.2 - y = 0.9 (using(1))
⇒ y = 3.2 - 0.9 = 2.3
Thus, the solution of system of equation is x = 3.2 and y = 2.3
