y=-\frac{1}{6}\times 9+\frac{5}{6}\times 3+4
Calculate 3 to the power of 2 and get 9.
y=\frac{-9}{6}+\frac{5}{6}\times 3+4
Express -\frac{1}{6}\times 9 as a single fraction.
y=-\frac{3}{2}+\frac{5}{6}\times 3+4
Reduce the fraction \frac{-9}{6} to lowest terms by extracting and canceling out 3.
y=-\frac{3}{2}+\frac{5\times 3}{6}+4
Express \frac{5}{6}\times 3 as a single fraction.
y=-\frac{3}{2}+\frac{15}{6}+4
Multiply 5 and 3 to get 15.
y=-\frac{3}{2}+\frac{5}{2}+4
Reduce the fraction \frac{15}{6} to lowest terms by extracting and canceling out 3.
y=\frac{-3+5}{2}+4
Since -\frac{3}{2} and \frac{5}{2} have the same denominator, add them by adding their numerators.
y=\frac{2}{2}+4
Add -3 and 5 to get 2.
y=1+4
Divide 2 by 2 to get 1.
y=5
Add 1 and 4 to get 5.
