1)

\frac{-1}{3} - \frac{-1}{2}

= \frac{-1}{3} + \frac{1}{2}

=(\frac{2}{2}) \frac{-1}{3} + (\frac{3}{3})\frac{1}{2}

= \frac{-2}{6} + \frac{3}{6}

= \frac{1}{6}

2)

-9\frac{1}{3} - (-1\frac{1}{3})

=-9\frac{1}{3} + 1\frac{1}{3}

=-\frac{3(9)+1}{3} + \frac{3(1) + 1}{3}

=\frac{-28}{3} + \frac{4}{3}

=\frac{-24}{3}

= -8

Solve this equation. 5n+7=7(n+1)-2n
Trava [24]
5n + 7 = 7(n+1) - 2n

First distribute 7 to all terms inside the parenthesis

7(n) = 7n
7(1) = 7

5n + 7 = 7n - 2n + 7

Simplify. Combine like terms

5n + 7 = 5n + 7

True.

If you want to continue:

Isolate the n, move all variables to one side, and constants to the other

5n (-5n) + 7 (-7) = 5n (-5n) + 7 (-7)

0 = 0

True
