Question 392237
{{{3vt+v(5v-7t)}}}
First you use distributive property to get rid of the parentheses.

{{{3vt+5v^2-7tv}}}
Because of the commutative property, -7tv = -7vt
So combine like terms (3vt and -7vt) to equal -4vt
{{{-4vt+5v^2}}} is as far as you can simplify the problem, because {{{3vt+v(5v-7t)}}} isn't set equal to a whole number.
