$$\frac { x + 1 } { 5 } + \frac { 2 x - 1 } { 4 }$$
Evaluate
$\frac{7x}{10}-\frac{1}{20}$
Short Solution Steps
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of $5$ and $4$ is $20$. Multiply $\frac{x+1}{5}$ times $\frac{4}{4}$. Multiply $\frac{2x-1}{4}$ times $\frac{5}{5}$.
