See a solution process below:

Explanation:

Step 1) Add color(red)(33.7)33.7 to each side of the equation to isolate the qq term while keeping the equation balanced:

-2.6q - 33.7 + color(red)(33.7) = 84.1 + color(red)(33.7)2.6q33.7+33.7=84.1+33.7

-2.6q - 0 = 117.82.6q0=117.8

-2.6q = 117.82.6q=117.8

Step 2) Divide each side of the equation by color(red)(-2.6)2.6 to solve for qq while keeping the equation balanced:

(-2.6q)/color(red)(-2.6) = 117.8/color(red)(-2.6)2.6q2.6=117.82.6

(color(red)(cancel(color(black)(-2.6)))q)/cancel(color(red)(-2.6)) = -45.307 rounded to the nearest thousandth.

q = -45.307 rounded to the nearest thousandth.
