See the entire solution process below;

Explanation:

First, subtract color(red)(3)3 from each side of the equation to isolate the ww term and keep the equation balanced:

w/7 + 3 - color(red)(3) = -1 - color(red)(3)w7+33=13

w/7 + 0 = -4w7+0=4

w/7 = -4w7=4

Now, multiply each side of the equation by color(red)(7)7 to solve for ww while keeping the equation balanced:

w/7 xx color(red)(7) = -4 xx color(red)(7)w7×7=4×7

w/color(red)(cancel(color(black)(7))) xx cancel(color(red)(7)) = -28

w = -28
