Question

rewrite each term as a product of 7 and another term. 14f - 21 = 7 ( f ) - 7 ( ? )

Explanation:

Step1: Factor out 7 from 14f

Since $14f\div7 = 2f$, we can write $14f$ as $7\times2f$.

Step2: Factor out 7 from 21

Since $21\div7=3$, we can write $21$ as $7\times3$.

Answer:

$14f - 21=7(2f)-7(3)$
