Solve "x" ..... 3/4 = x/84
First: eliminate the fractions - multiply the denominators with each term.
(4)(84)(3/4) = (4)(84)(x/84)
SEc: cross cancel "like" terms & combine the remaining terms.
(84)(3) = (4)(x)
252 = 4x
Or, the equation can also be written as....
4x = 252
Third: isolate "x" on one side - divide both terms by 4.
4x/4 = 252/4
x = 252/4
x = 63

cross multiply
giving you 4x=252
x=63
which is intuitively correct, if you simply divide 84 by 4 you get 21, multiply this by 3 and you get 63

X=63 becasue you divide 84 by 4 and then multiply that number by three to get your answer.

ah, let's see!
First isolate x by multiplying both sides by 84
(84)*3/4=x/84*84
which reduces to
84*3/4=x
252/4=x
63=x
