Yes, considering the fact that the number line can contain any number.
13: answer is x= —4
14: answer is x= 1/3, x= 2
5 is the answer to the problem
P = 6
Q = 15
How to solve:
Note the equal sign. This means that both expression's out come must equal each other. For that to happen, everything inside both expressions must equal each other. In this case:
6x + Q = Px + 15; 6x + 15 = 6x + 15
hope this helps
