Divide each side of the equation by $7.9$ to solve for $r$ while keeping the equation balanced. See below

Divide each side of the equation by $color(red)(7.9)$ to solve for $r$ while keeping the equation balanced.

$(7.9r)/color(red)(7.9) = -19.75/color(red)(7.9)$

$(color(red)(cancel(color(black)(7.9)))r)/cancel(color(red)(7.9)) = -2.5$

$r = -2.5$
