Question

W=fd
Solve for F
Then it asks the same question but to solve next time for D

Answer 1

w = fd   Divide both sides by d
$\frac{w}{d}$ = f   Switch the sides to make it easier to read
f = $\frac{w}{d}$

w = fd   Divide both sides by f
$\frac{w}{f}$ = d   Switch the sides to make it easier to read
d = $\frac{w}{f}$

Answer 2

Work=force*distance

Solve for force: simply rearrange the equation. Move distance over to isolate force to get
force= work/distance

solve for distance: rearrange equation again.
Move force over to isolate distance to get
Distance= work/force
