Solve each equation. check you solution.

(7t - 2) - (-3t + 1) = - 3 (1 - 3t)

(7t-2) - (-3t+1) = - 3 * (1-3t)

First distribute:

7t-2+3t-1 = - 3+9t

Now get all the terms with 't' on the same side by subtracting/adding:

7t+3t-9t = - 3+2+1

Combine the terms:

1t=0

t=0

Check:

Plug in 0 for t and see if both sides of the equation come out the same:

Does (7 (0) - 2) - (-3 (0) + 1) = - 3 (1-3 (0)) ?

(-2) - (1) = - 3 (1) ?

-3 = - 3?

Yes! It works, so t=0!
