-4t-\frac{4t}{15}+\frac{18}{3}+\frac{2}{3}
Convert 6 to fraction \frac{18}{3}.
-4t-\frac{4t}{15}+\frac{18+2}{3}
Since \frac{18}{3} and \frac{2}{3} have the same denominator, add them by adding their numerators.
-4t-\frac{4t}{15}+\frac{20}{3}
Add 18 and 2 to get 20.
-4t-\frac{4t}{15}+\frac{20\times 5}{15}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 15 and 3 is 15. Multiply \frac{20}{3} times \frac{5}{5}.
-4t+\frac{-4t+20\times 5}{15}
Since -\frac{4t}{15} and \frac{20\times 5}{15} have the same denominator, add them by adding their numerators.
-4t+\frac{-4t+100}{15}
Do the multiplications in -4t+20\times 5.
\frac{15\left(-4\right)t}{15}+\frac{-4t+100}{15}
To add or subtract expressions, expand them to make their denominators the same. Multiply -4t times \frac{15}{15}.
\frac{15\left(-4\right)t-4t+100}{15}
Since \frac{15\left(-4\right)t}{15} and \frac{-4t+100}{15} have the same denominator, add them by adding their numerators.
