Question 773601
<font face="Times New Roman" size="+2">


What is to solve?  The statement is an identity; it is true for all real values of *[tex \LARGE t].


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 13t\ -\ (5\ -\ 2t)\ =\ 5(3t\ -\ 1)]


Apply the distributive property:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 13t\ -\ 5\ +\ 2t\ =\ 15t\ -\ 5]


Collect like terms:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 15t\ -\ 5\ =\ 15t\ -\ 5]


Add 5 to both sides


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 15t\ =\ 15t]


Multiply by *[tex \LARGE \frac{1}{15}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ t\ =\ t]


Which is true *[tex \LARGE \forall t\ \in\ \mathbb{R}]
