Question: Is(2,1/2) a solution of the linear equation x = 4y
Sol: Given (2,1/2) 
⇒x = 2  and y=1/2
Given equation: x = 4y
x - 4y = 0
Substituting x and y value in the given equation
⇒2 - 4(1/2) = 0
⇒2 - 4/2 = 0 
⇒2 - 2 = 0 
⇒0 = 0
⇒0 =0
∴(2,1/2) is a solution of the given equation
0

If the solution is: (2,1/2).
⇒x=2, y=1/2
Equation is x=4y
⇒2=4(1/2)
⇒2=2
hence the solution is correct.
