I'm confused at how to do this?

Use interval notation to express the solution set and graph the solution set on a number line.

((x-18)/6)or equal to ((x-9)/9)+(1/18)

I'm confused at how to do this?

Use interval notation to express the solution set and graph the solution set on a number line.

((x-18)/6)>or equal to ((x-9)/9)+(1/18)

anonymous · Answer

$$\frac{x-18}{6}\geq \frac{x-9}{9}+\frac{1}{18}$$ start by multiplying both sides by 18 to get 
$$3(x-18)\geq2(x-9)+1$$

anonymous · Answer

You have an inequality equation. Treat it as a normal equation, except when multipling or dividing both sides with a negative number, you have to "flip" the >= sign.

Thank you both!!

Do you know what its solution set is? Like (-37, infinity) ?

anonymous · Answer

then multiply out to get 
$$3x-54\geq 2x-18+1$$
$$x\geq 54-18+1$$
$$x\geq 37$$

anonymous · Answer

think it is 
$$[37,\infty)$$

anonymous · Answer

unless i made an algebra mistake

Right, didnt mean to put the "-". Thanks!
