Y=3x+3
They did 1/3 instead of 3/1
We can't find what PT exactly is because we don't know TQ or x. However, we can find PT in terms of TQ!
Multiply the second equation by seven sixths to get:

Subtract

from both sides to get:

Substituting PT for 7x-24, we see that:

, which is our answer.
7 + 2x - 6 = -3x - 3 - 4
2x + 1 = -3x - 3 - 4
2x + 1 = -3x - 7
2x + 1 + 3x = -7
5x + 1 = -7
5x = -7 - 1
5x = -8
x = -8/5.
