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. what can vineet conclude?

He can conclude that the system of equations has no solution since one equation in it always results with false equivalency.

Hope this helps.

He can conclude that the system of equations is inconsistent, i.e. it has no solution.

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.

Hence, the system of equations is inconsistent , it has no solution.

step-by-step explanation:

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
