Question

Solve the inequalities. Graph the solution.1. 7x – 3 > 18 or 3x – 2 <-2

Answer 1

`\begin{gathered} 7x-3>18\text{ \backslash +3 } \\ 7x>21\text{ \backslash divide by 7} \\ x>3 \end{gathered}`
`\begin{gathered} 3x-2<-2\text{ \backslash +2} \\ 3x<0\text{ \backslash divide by 3} \\ x<0 \end{gathered}`

So x<0 and x>3 this means that x is either less tha zero or greater than 3

If you draw it in the number line:
