x+\frac{3}{2}+2\times \frac{3}{x}+\frac{4x}{1}
Anything divided by one gives itself.
x+\frac{3}{2}+\frac{2\times 3}{x}+\frac{4x}{1}
Express 2\times \frac{3}{x} as a single fraction.
x+\frac{3}{2}+\frac{2\times 3}{x}+4x
Anything divided by one gives itself.
5x+\frac{3}{2}+\frac{2\times 3}{x}
Combine x and 4x to get 5x.
5x+\frac{3x}{2x}+\frac{2\times 2\times 3}{2x}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 2 and x is 2x. Multiply \frac{3}{2} times \frac{x}{x}. Multiply \frac{2\times 3}{x} times \frac{2}{2}.
5x+\frac{3x+2\times 2\times 3}{2x}
Since \frac{3x}{2x} and \frac{2\times 2\times 3}{2x} have the same denominator, add them by adding their numerators.
5x+\frac{3x+12}{2x}
Do the multiplications in 3x+2\times 2\times 3.
\frac{5x\times 2x}{2x}+\frac{3x+12}{2x}
To add or subtract expressions, expand them to make their denominators the same. Multiply 5x times \frac{2x}{2x}.
\frac{5x\times 2x+3x+12}{2x}
Since \frac{5x\times 2x}{2x} and \frac{3x+12}{2x} have the same denominator, add them by adding their numerators.
\frac{10x^{2}+3x+12}{2x}
Do the multiplications in 5x\times 2x+3x+12.
