First, rewrite the numerator of the fraction on the left side of the equation. Remember, minus a minus is a plus:
(-4h + 5)/-7 = 13
Next, multiply each side of the equation by color(red)(-7) to eliminate the fraction while keeping the equation balanced:
color(red)(-7) xx (-4h + 5)/-7 = color(red)(-7) xx 13
cancel(color(red)(-7)) xx (-4h + 5)/color(red)(cancel(color(black)(-7))) = -91
-4h + 5 = -91
Then, subtract color(red)(5) from each side of the equation to isolate the h term while keeping the equation balanced:
-4h + 5 - color(red)(5) = -91 - color(red)(5)
-4h + 0 = -96
-4h = -96
Now, divide each side of the equation by color(red)(-4) to solve for h while keeping the equation balanced:
(-4h)/color(red)(-4) = (-96)/color(red)(-4)
(color(red)(cancel(color(black)(-4)))h)/cancel(color(red)(-4)) = 24
h = 24
