(12/x) + (3/4) = 3/2
The best way to solve this is to multiply both sides of the equation by the lowest common denominator of x, 4, and 2. The lowest common denominator is 4x, so if we look at each term, multiply by 4x, and determine what cancels and what stays, we will have succeeded in eliminating all fractions.
12(4) + 3x = 6x
Simplify,
48 + 3x = 6x
48 = 3x
Therefore,
x = 16

12/x + 3/4 = 3/2
12/x = 3/2 - 3/4
12/x = 6/4 - 3/4
12/x = 3/4
12 * 4 = 3x
48 = 3x
16 = x

12/x+3/4=3/2
12/x=3/2-3/4
12/x=6/4-3/4
12/x=3/4
x(12/x)=x(3/4)
12=3x/4
12*4=3x
48=3x
x=16
