Solve 4-1+2x/10

$$4 - 1 + 2 \frac { x } { 10 }$$

Evaluate

$$\frac{x}{5}+3$$

Short Solution Steps

Subtract 1 from 4 to get 3.

$$3+2\times \frac{x}{10}$$

Cancel out 10, the greatest common factor in 2 and 10.

$$3+\frac{x}{5}$$

To add or subtract expressions, expand them to make their denominators the same. Multiply 3 times \frac{5}{5}.

$$\frac{3\times 5}{5}+\frac{x}{5}$$

Since \frac{3\times 5}{5} and \frac{x}{5} have the same denominator, add them by adding their numerators.

$$\frac{3\times 5+x}{5}$$

Do the multiplications in 3\times 5+x.

$$\frac{15+x}{5}$$

Factor

$$\frac{x+15}{5}$$

Solution Steps

Factor out \frac{1}{5}.

$$\frac{15+x}{5}$$

Consider 20-5+x. Multiply and combine like terms.

$$x+15$$

Rewrite the complete factored expression.

$$\frac{x+15}{5}$$
