Mounting sd to internal memory

Lets hope I'm in the right forum this time :) I created a thread in the assist forum but they told me to start from here. I guess they think I have a better chance to find an answer. Here it goes.

I have a tablet ZTE E9Q witch it has a very small amount of memory. Only 1gb and already the system took 900mb incliding factory apps. I need to edit the vold.fstab in order to increase the internal memory.I have watched videos on youtube and read a few threds and post here but I still can't figure it out. The lines are not the same as the ones a saw. Can anyone help me please?
This is the code.
ps: I already tried to swap 0 and 1 in the first and the second line but I got nothing.Still was the same.

Example of a standard sdcard mount for the emulator / Dream
# Mounts the first usable partition of the specified device
dev_mount sdcard /storage/sdcard0 emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-msdc.0/mmc_host
dev_mount sdcard2 /storage/sdcard1 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.1/mmc_host
## Example of a dual card setup
# dev_mount left_sdcard /mnt/sdcard1 auto /devices/platform/goldfish_mmc.0 /devices/platform/mtk-sd.0/mmc_host/mmc0
# dev_mount right_sdcard /mnt/sdcard2 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-sd.2/mmc_host/mmc2

## Example of specifying a specific partition for mounts
# dev_mount sdcard /mnt/sdcard 2 /devices/platform/goldfish_mmc.0 /devices/platform/msm_sdcc.2/mmc_host/mmc1
