Question #ac4ab

Answer 1

`-4a + 12x`

Explanation:

To simplify this, you have to combine the like terms.
`(-a - 3a) + (2x + 10x)`
`-4a + 12x`

Answer 2

`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`

Answer 3

Please see answer below..

Explanation:

`-a + 2x + 10x -3a`

Collect like terms..

`-a -3a +2x + 10x`

`-4a +12x`

`-4(a - 3x)`
