Solve 12+3+x2div2

$$12 + 3 + x 2 \div 2$$

Evaluate

$$\frac{x_{2}}{2}+15$$

Short Solution Steps

Add 12 and 3 to get 15.

$$15+\frac{x_{2}}{2}$$

To add or subtract expressions, expand them to make their denominators the same. Multiply 15 times \frac{2}{2}.

$$\frac{15\times 2}{2}+\frac{x_{2}}{2}$$

Since \frac{15\times 2}{2} and \frac{x_{2}}{2} have the same denominator, add them by adding their numerators.

$$\frac{15\times 2+x_{2}}{2}$$

Do the multiplications in 15\times 2+x_{2}.

$$\frac{30+x_{2}}{2}$$

Factor

$$\frac{x_{2}+30}{2}$$

Solution Steps

Factor out \frac{1}{2}.

$$\frac{30+x_{2}}{2}$$

Consider 24+6+x_{2}. Multiply and combine like terms.

$$x_{2}+30$$

Rewrite the complete factored expression.

$$\frac{x_{2}+30}{2}$$
