200 = r/3 : Multiply both sides by 3
600 = r and this gives the answer.
Where you have just one unknown (in this question it is "r") then operate on the equation to produce a single quantity of the unknown. This has been completed in one step but other equations may involve several, more complex steps.
R/4 = 1/3 r/4*4 = 1/3 *4 r=4/3

I = v/r
200.7333
if r=5z and 15z =3 then r=10y
d=r/t (D equals r divided on t
5
I
r = 5z 15z = 3y (divide by 3 to both sides) 5z = y r = y
