Question

-4+w+ 17-2/3 W = 16

Answer 1

`\begin{gathered} -4+w+17-(2)/(3)w=16 \\ w-(2)/(3)w+17-4=16 \\ (1-(2)/(3))w+13=16 \\ (1-(2)/(3))w=16-13 \\ (1-(2)/(3))w=3 \\ ((3)/(3)-(2)/(3))w=3 \\ ((3-2)/(3))w=3 \\ (1)/(3)w=3 \\ w=3\cdot3 \\ w=9 \end{gathered}`
`\begin{gathered} -12c-4+7.4c-11=-6 \\ -4.6c-15=-6 \\ -4.6c=-6+15 \\ -4.6c=9 \\ c=-(9)/(4.6) \\ c=-1.95 \end{gathered}`
