Question

So I joined a ged class and this is apparently a “high school level” math problem, maybe for people in advanced classes but not regular. Anyway, I need help with solving this. Also the greater than sign with the problem that I’m doing has like an underline under it, which I think means greater than or equal to 3x + 9 > - x + 19

Answer 1

Given the inequality:

`3x+9\ge-x+19`

Solve for x:

`\begin{gathered} 3x+x\ge19-9 \\ 4x\ge10 \\ x\ge(10)/(4) \\ \\ x\ge(5)/(2) \end{gathered}`

so, the answer will be:

`\begin{gathered} x\ge(5)/(2) \\ x\in\lbrack(2)/(5),\infty) \end{gathered}`
