I cannot access all of my hard drive space on my OSX.

Question

When I bought my Macbook Air in 2012, the hard drive was already partitioned into two parts one OS and the other OSX. The OSX part with the operation system only contains about 30 GB of memory, while the other partition has 90 GB. I deleted the second partition to try to put all the memory in the OSX partition of my hard drive, but found that I cannot do so. The OSX portion cannot be increased from the DIsk Utility page. I was hoping someone could help me fix this problem because I need the the extra space to download programming environments that work with the operating system. I attached some pictures of what my storage space currently looks like.

Open Disk Utility, click on the GB Apple SSD device in the sidebar and click on the Partition tab in the main window. Click on the topmost partition in the map then click on the Add [+] button to create a new volume. Click on the Apply button.
Use Carbon Copy Cloner 4.0.5 to clone the OS X volume to the newly created volume. When completed open Startup Disk preferences. Click on the new volume entry then click on the Restart button. Once running from the newly made clone you can now open Disk Utility, click in the old OS X partition then click on the Delete [-] button to remove it. You can now drag the top partition down to fill the empty space. Click on the Carbon Copy Cloner 4.0.5 button.
You are moving your OS around when you do this. You may want to take a backup before you begin - if anything goes wrong you have a way recover. Time Machine is OK, but a bootable copy is better. Carbon Copy Cloner will also do that for you, make one to an external disk to be safe.
