Question

simplify 21/5x+12-6/2-5/2x

Answer 1

Answer:

(17/10)x+9

Explanation:

Given the expression

$\frac{21}{5}x+12-\frac{6}{2}-\frac{5}{2}x$

We rearrange by bringing all the constants together.

$\begin{gathered} \frac{21}{5}x-\frac{5}{2}x+12-\frac{6}{2} \\ =\frac{42x-25x}{10}+12-3 \\ =\frac{17}{10}x+9 \end{gathered}$
