How to solve 3+(2B)/(A-B)

1. Factor the equation (x + 2)(x + 3) = 0. 2. Set each factor equal to zero: x + 2 = 0 and x + 3 = 0. 3. Solve for x: x = -2 and x = -3.

Question

$$3+ \frac{ 2B }{ A-B }$$

Evaluate

$\frac{3A-B}{A-B}$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply $3$ times $\frac{A-B}{A-B}$.

$$\frac{3\left(A-B\right)}{A-B}+\frac{2B}{A-B}$$

Since $\frac{3\left(A-B\right)}{A-B}$ and $\frac{2B}{A-B}$ have the same denominator, add them by adding their numerators.

$$\frac{3\left(A-B\right)+2B}{A-B}$$

Do the multiplications in $3\left(A-B\right)+2B$.

$$\frac{3A-3B+2B}{A-B}$$

Combine like terms in $3A-3B+2B$.

$$\frac{3A-B}{A-B}$$
