Question

(2,3) is a solution of the equation 3x-2y-7=0. give reason​

Answer 1

Answer:

$(2,3)$ is not a solution of equation $3x-2y-7=0$.        

Step-by-step explanation:

Given : The expression is $3x-2y-7=0$

           The solution of the equation is $(2,3)$.

To find : We have to give reason for the solution of the given expression.

Solution :

• It is given that the given expression is $3x-2y-7=0$.
• The solution of the equation is $(2,3)$ .
• We have to give reason for the solution of the given expression.
• The given expression contains the variables $x$ and $y$ and the values of $x$ and $y$ is given as  $(2,3)$.
• If these values of $x$ and $y$ satisfies the given solution, then the solution of the given expression is correct.
• We have to put $x=2$ and $y=3$ in given expression and have to check whether L.H.S. = R.H.S. or not.
• The equation becomes,

            $3x-2y-7=0$

    ∴ $3*2-2*3-7=0$

             ∴ $6-6-7=0$

                     ∴ $-7=0$

                ∴ L.H.S. ≠ R.H.S.

• ∴ $(2,3)$ is not a solution of equation $3x-2y-7=0$.              

Answer 2

(2,3)is not the solution of the given equation 3x-2y-7.

Here x =2 and y = 3

Putting value in L. H. S,

= 3×2 -2×3-7

= 6-6-7

= -7

In R.H.S , =0

Therefore L. H. S is not equal to R.H.S
