To solve for w, we need to isolate it on one side of the equation.
-7.9 = -3.1 + w/3
First, we can get rid of the fraction by multiplying both sides of the equation by 3:
3*(-7.9) = 3*(-3.1) + 3*(w/3)
-23.7 = -9.3 + w
Next, we can simplify the right side of the equation:
-23.7 = -9.3 + w
To isolate w, we can subtract -9.3 from both sides of the equation:
-23.7 - (-9.3) = -9.3 - (-9.3) + w
-23.7 + 9.3 = 0 + w
-14.4 = w
Therefore, w = -14.4.
-7.9 = -3.1 + w/3
