Dave has X markers, so Sheila has 5X markers. 
Adding up all markers, X + 5X = 6X.
There are 18 markers, so 6X=18. 
Dividing both sides of that equation by 6, we get X=3.
5X is 15.
So Dave has 3 markers and Sheila has 15 markers, for a total of 18 markers.
Hi Kesia;
Let's divide both sides by 6...
3 + 15 = 18
Dave's markers + Sheila's markers =18 markers
