Question

Fill in the boxes to add the expressions. 5 n - 14 + 1 n + 17 = ( + + -)+(-14+ 7 II __n+

Answer 1

$(\frac{5}{7}n-14)+(\frac{1}{7}n+17)$

combine like terms

$(\frac{5}{7}n+\frac{1}{7}n)+(-14+17)$$\begin{gathered} \frac{5}{7}n+\frac{1}{7}n=\frac{5n+1n}{7}=\frac{6}{7}n \\ -14+17=3 \\ \\ \frac{6}{7}n+3 \end{gathered}$
