3/17x=12

(3/17)x=12
x = 12/(3/17)
x = 12 * (17/3)
x = 204/3 = 68

(3/17)x = 12
to get x alone, you divide both sides by the numerical coefficient (number before the variable) of x. 3/17 divided by itself is 1 and thus thus
x = 12 / (3/17)
to divide by fraction, you get the reciprocal of the divisor (that is, the 3/17) and change the division operation to multiplication:
x = 12 * 17/3
x = 68
hope this helps~ :)
