12x-4a

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 a, and two including a x.

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

2x+10x-a-3a

The a can be substituted to show 1a.

2x+10x-1a-3a

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

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