See the entire solution process below:

Step 1) Add $color(red)(0.7)$ to each side of the equation to isolate the $m$ term while keeping the equation balanced:

$0.4m - 0.7 + color(red)(0.7) = 0.22 + color(red)(0.7)$

$0.4m - 0 = 0.92$

$0.4m = 0.92$

Step 2) Divide each side of the equation by $color(red)(0.4)$ to solve for $m$ while keeping the equation balanced:

$(0.4m)/color(red)(0.4) = 0.92/color(red)(0.4)$

$(color(red)(cancel(color(black)(0.4)))m)/cancel(color(red)(0.4)) = 2.3$

$m = 2.3$
