Question

3.5(c + 7) = 15(c - 3)

Answer 1

The given inequality is,

`5(c+7)\leq15(c-3)`

The inequality can be solved as,

`\begin{gathered} 5c+5*7\leq15c-15*3 \\ 5c+35\leq15c-45 \\ 35+45\leq15c-5c \\ 80\leq10c \\ (80)/(10)\leq c \\ 8\leq c \end{gathered}`

The solution of the inequality is 8≤ c.
