Question

Subtract the second expressions from the first expressions.

-7a+3;6a-9

Answer 1

First expression is -7a + 3
And second expression is 6a - 9
Subtracting the second expression from first we get;
$$\begin{gathered} -7a+3-\left(6a-9\right) \\ =-7a+3-6a+9 \\ =-7a-6a+3+9 \\ =-13a+12 \end{gathered}$$
