#### Answer

Subtract 4.2 from each side.

#### Work Step by Step

To solve an inequality, you need to isolate the variable on one side of the inequality.
$6.8\geq m+4.2\longrightarrow$ subtract 4.2 from each side to isolate m on the right side.
$6.8-4.2\geq m+4.2-4.2\longrightarrow$ subtract
$2.6\geq m$
