Answer:</h2>
He can conclude that the system of equations is inconsistent, i.e. it has no solution.
<h2>
Step-by-step explanation:</h2>
We know that we get a no solution when we get a expression which is always false.
Here,
Vineet solved a system of equations by substitution.
In his work, he substituted an expression for one of the variables and solved for the value of the other.
This resulted in the equation 7 = 9.
which is a false identity.
since 7 can never be equal to 9.
<em>Hence, the system of equations is inconsistent , it has no solution.</em>
