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?
The solution to the system is (7, 9).
The system of equations does not have a solution.
The work must be incorrect because it is not possible to get this equation.
The system of equations has infinitely many solutions.

The system of equations does not have a solution.

For example, imagine these two equations y = x + 7 and y = x + 9

Now subsitute y in the second equation with the value from the first equation:

x + 7 = x + 9

x - x + 7 = 9

0 + 7 = 9

7 = 9.

That happens because the equations represent parallel lines, which do not have a common pair of points.

The thing which Vineet can conclude is:

  • B. The system of equations does not have a solution.

That happens because the equations represent parallel lines, which do not have a common pair of points.

Equation

This refers to the statement in mathematics which shows the equality of two expressions using the = sign

With this in mind, we can see that if we expand the system of equations, it does not have a solution

Therefore, the correct answer is option B
