Question

Simplify the expression.

$m+5-2\left(m+7\right)$

Short answer

The value of the expression is $-\left(m+9\right)$.

Step-by-step solution

Step 1. Given information

The expression is $m+5-2\left(m+7\right)$

Step 2. Calculation 

Simplify the expression

Therefore,

$\begin{array}{c}m+5-2\left(m+7\right)=m+5-2m-14\\ =-m-9\\ =-\left(m+9\right)\end{array}$

Thus, the value of the expression is $-\left(m+9\right)$.
