Answer: t = 3
To solve this equation, first, distribute the 70 across (7 - t). This creates the equation [tex]35t+490-70t=385[/tex]. Collecting like terms and subtracting 490 from both sides of the equation makes [tex]-35t=-105[/tex]. To finish solving for t, all you have to do now is divide by -35: [tex] \frac{-35t}{-35} = \frac{-105}{-35} [/tex], [tex]t=3[/tex].
