is (2,1) a solution of a equation x-2y=0
Answers
Answer:
If (2,1) is a solution then it must satisfy this equation
x = 2
y = 1
So x - 2y = 2 - 2(1) = 0
So (2,1) is a solution of this equation.

Step-by-step explanation:
Here is your answer
_____________________________________________________________
X = 2y
so, x - 2y = 0
and 2x - y = 0
so, 1/2 ≠ 2/1
a1/a2 ≠ b1/b2
so, these pair of eqn has one unique solution which is x =0 and y = 0

Which pair of given values is the solution of linear equation; x-2y=0
(a) (1,2)
(b) (0,1)
(c) (2,1)
(Complete question)
Given:
x-2y = 0
To find:
The solution of the linear equation
Solution:
1) A linear equation has infinitely many solutions that satisfy the linear equation.
2) We have the option so we just put the value of one in the given equation to check whether it is satisfying the equation or not.
x-2y = 0
(1,2)
Put the value of x
1-2y = 0
2y=1
y = 1/2
2≠1/2
(0,1)
Put the value of x
x-2y = 0
0 - 2y = 0
y=0
2≠0
(2,1)
Put the value of x
x-2y=0
2-2y = 0
2y = 2
y=1
1=1
This satisfies the given equation.
