Aww. Advanced Functions. NotTim's Weakness.

jim_thompson5910 · Answer

3x+11 > 26


3x > 26-11


3x > 15


x > 15/3


x > 5


So the solution is x > 5


To graph this, draw out a number line and draw an open circle at 5. Then shade to the right of that open circle.

You're welcome

wait...jim...you got the time to teach me how you did this?

jim_thompson5910 · Answer

The idea is to solve this as if you would any equation. So if you can solve 3x+11 = 26, then you can solve 3x+11 > 26


Just think of the ">" as a "=". The sign will only change if you happen to multiply or divide both sides by a negative number.

Instead of an open circle, use a closed circle.

except the line would be directly underneath the greater to sin
