Question

PT=7x-24 and TQ=6x-2, Find PT.

Answer 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:


`(7TQ)/(6)=7x- (7)/(3)`

Subtract
`(65)/(3)` from both sides to get:


`(7TQ)/(6)- (65)/(3)=7x-24`

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


`PT= (7TQ)/(6) - (65)/(3)`, which is our answer.
