$- 4 a + 12 x$ $-4a + 12x$

Explanation:

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

Answer 2 · 2017-11-05T23:15:46

$12 x - 4 a$ $12x-4a$

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 $a$ $a$ , and two including a $x$ $x$ .

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

$2 x + 10 x - a - 3 a$ $2x+10x-a-3a$

The $a$ $a$ can be substituted to show $1 a$ $1a$ .

$2 x + 10 x - 1 a - 3 a$ $2x+10x-1a-3a$

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

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

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: $12 x - 4 a$ $12x-4a$

Please see answer below..

Explanation:

$- a + 2 x + 10 x - 3 a$ $-a + 2x + 10x -3a$

Collect like terms..

$- a - 3 a + 2 x + 10 x$ $-a -3a +2x + 10x$

$- 4 a + 12 x$ $-4a +12x$

$- 4 (a - 3 x)$ $-4(a - 3x)$
