3\left(-\frac{15}{2}+\frac{2}{2}\right)-2\left(-\frac{15}{2}\right)+5-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
Convert 1 to fraction \frac{2}{2}.
3\times \frac{-15+2}{2}-2\left(-\frac{15}{2}\right)+5-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
Since -\frac{15}{2} and \frac{2}{2} have the same denominator, add them by adding their numerators.
3\left(-\frac{13}{2}\right)-2\left(-\frac{15}{2}\right)+5-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
Add -15 and 2 to get -13.
\frac{3\left(-13\right)}{2}-2\left(-\frac{15}{2}\right)+5-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
Express 3\left(-\frac{13}{2}\right) as a single fraction.
\frac{-39}{2}-2\left(-\frac{15}{2}\right)+5-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
Multiply 3 and -13 to get -39.
-\frac{39}{2}-2\left(-\frac{15}{2}\right)+5-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
Fraction \frac{-39}{2} can be rewritten as -\frac{39}{2} by extracting the negative sign.
-\frac{39}{2}-\left(-15\right)+5-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
Cancel out 2 and 2.
-\frac{39}{2}+15+5-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
The opposite of -15 is 15.
-\frac{39}{2}+\frac{30}{2}+5-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
Convert 15 to fraction \frac{30}{2}.
\frac{-39+30}{2}+5-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
Since -\frac{39}{2} and \frac{30}{2} have the same denominator, add them by adding their numerators.
-\frac{9}{2}+5-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
Add -39 and 30 to get -9.
-\frac{9}{2}+\frac{10}{2}-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
Convert 5 to fraction \frac{10}{2}.
\frac{-9+10}{2}-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
Since -\frac{9}{2} and \frac{10}{2} have the same denominator, add them by adding their numerators.
\frac{1}{2}-\frac{35}{2}=10\left(-\frac{3}{2}\right)-10+8
Add -9 and 10 to get 1.
\frac{1-35}{2}=10\left(-\frac{3}{2}\right)-10+8
Since \frac{1}{2} and \frac{35}{2} have the same denominator, subtract them by subtracting their numerators.
\frac{-34}{2}=10\left(-\frac{3}{2}\right)-10+8
Subtract 35 from 1 to get -34.
-17=10\left(-\frac{3}{2}\right)-10+8
Divide -34 by 2 to get -17.
-17=\frac{10\left(-3\right)}{2}-10+8
Express 10\left(-\frac{3}{2}\right) as a single fraction.
-17=\frac{-30}{2}-10+8
Multiply 10 and -3 to get -30.
-17=-15-10+8
Divide -30 by 2 to get -15.
-17=-25+8
Subtract 10 from -15 to get -25.
-17=-17
Add -25 and 8 to get -17.
\text{true}
Compare -17 and -17.
