Answer

$m=-4$

Work Step by Step

We are given the equation $m-2+18=|-3-4|+5$. In order to solve, we can first combine like terms on the left side. $m-2+18=m+16=|-3-4|+5$ Combine like terms on the right side. $m+16=|-3-4|+5=|-7|+5=7+5=12$ Subtract 16 from both sides. $m+16-16=12-16$ $m+0=-4$ $m=-4$
