Answer:

<h2>There is no solution since 4 = 7 is a false statement.</h2>

Step-by-step explanation:

Let's check Jane's solution.

13 + 4x - 9 = 7x + 7 - 3x           <em>combine like terms</em>

4x + (13 - 9) = (7x - 3x) + 7

4x + 4 = 4x + 7          <em>subtract 4x from both sides</em>

4x - 4x + 4 = 4x - 4x + 7

4 = 7    FALSE

Answer:

There is no solution since 4=7 is a false statement.

Step-by-step explanation:

This is an automatic giveaway. Think about what would happen if you were to graph these lines on a grid. These lines are parallel lines, and parallel have SIMILAR <em>RATE</em><em> </em><em>OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>], which in this case is 4 [next to the <em>x</em>]. This is what is called an Inconsistent<em> </em>System<em> </em>of equations.

I am joyous to assist you anytime.
