12x-4a12x4a

Explanation:

When simplifying equations such as this one, it is key to look for common factors. In the original equation, you can see that there are two terms (numbers) including an aa, and two including a xx.

When rearranged to place these two pairs together, the equation looks like this:

2x+10x-a-3a2x+10xa3a

The aa can be substituted to show 1a1a.

2x+10x-1a-3a2x+10x1a3a

It is now simply a matter of logic. xx terms can be added together, as can aa terms.

2x+10x=12x2x+10x=12x
-1a-3a=-4a1a3a=4a

Once the two groups are put together as two singular terms, you can put them together as an equation. When adding a negative, the number is subtracted from the amount it was to be added to.

Therefore, the answer is: 12x-4a12x4a
