Solve y-1+3y/3

$$y - \frac { 1 + 3 y } { 3 }$$

Evaluate

$$-\frac{1}{3}\approx -0.333333333$$

Short Solution Steps

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

$$\frac{3y}{3}-\frac{1+3y}{3}$$

Since \frac{3y}{3} and \frac{1+3y}{3} have the same denominator, subtract them by subtracting their numerators.

$$\frac{3y-\left(1+3y\right)}{3}$$

Do the multiplications in 3y-\left(1+3y\right).

$$\frac{3y-1-3y}{3}$$

Combine like terms in 3y-1-3y.

$$\frac{-1}{3}$$

Fraction \frac{-1}{3} can be rewritten as -\frac{1}{3} by extracting the negative sign.

$$-\frac{1}{3}$$

Factor

$$-\frac{1}{3} = -0.3333333333333333$$
