Answer:

x = 3

Step-by-step explanation:

First, add 3 from both sides of the equation. This will leave you with 9x = 5x + 12. Next, Subtract 5x from both sides of the equation. This leaves you with 4x = 12 After that, divide both sides by 4. That will give you the answer x = 3.

Answer: $\frac{2x}{15}$

This is the fraction 2x/15 which can be read as 2x over 15

=====================================================

Work Shown:

Divide $\frac{14x^2}{15}$ over $7x$ to get

$\frac{14x^2}{15} \div 7x = \frac{14x^2}{15} \div \frac{7x}{1}\\\\\frac{14x^2}{15} \div 7x = \frac{14x^2}{15} \times \frac{1}{7x}\\\\\frac{14x^2}{15} \div 7x = \frac{14x^2*1}{15*7x}\\\\\frac{14x^2}{15} \div 7x = \frac{7x*2x*1}{15*7x}\\\\\frac{14x^2}{15} \div 7x = \frac{2x}{15}\\\\$

You can think of it as dividing 14x^2 over 7x and that results in 2x. Then you place that result (2x) over 15 to end up with 2x/15
