Q + 5/9= 1/6 from big ideas mathbook

Alika [10]

9We have such eqation
Q $+ \frac{5}{9} = \frac{1}{6}$ /*9 (multiply both sides by 9)
9Q+5= $\frac{9}{6}$ /-5 both sides
9Q= $\frac{9}{6}- 5$
9Q= $\frac{9}{6}- \frac{5*6}{6}$
9Q= $\frac{9-30}{6}$
9Q=- $\frac{21}{6}$ /:9 divide both sides by 9
Q=- $\frac{21}{6}:9$
Q $\frac{21}{6*9} =- \frac{21}{54}=[tex] \frac{7}{18}$ - its the answer
