Solve t-1+st/3

$$t - 1 + \frac { s t } { 3 }$$

Evaluate

$$\frac{st}{3}+t-1$$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply t-1 times \frac{3}{3}.

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

Since \frac{3\left(t-1\right)}{3} and \frac{st}{3} have the same denominator, add them by adding their numerators.

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

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

$$\frac{3t-3+st}{3}$$

Factor

$$\frac{st+3t-3}{3}$$

Solution Steps

Factor out \frac{1}{3}.

$$\frac{3t-3+st}{3}$$
