Question

Write an expression with at least 3 terms that simplifies to 7j - 13

Answer 1

To solve the exercise you can rewrite 7j as

$j+3j+9j-6j$

and rewrite -13 as

$-20+7$

Therefore, the expression that when simplifying it will give as a result 7j-13 will be

$j+3j+9j-6j-20+7$

because if you simplify you get:

$\begin{gathered} j+3j+9j-6j-20+7=13j-6j-13 \\ j+3j+9j-6j-20+7=7j-13 \end{gathered}$
