Question

SIMPLIFY- Algebra
-5-2x-3-x
I have -7x-3 so far but I’m not sure

Answer 1

Explanation

• Given the expression.

$- 5 - 2x - 3 - x$

• Simplify

Remind that a constant cannot add up or subtract with a variable term. Instead we just leave them.

$- 2x - x - 5 - 3 = - 3x - 8$

We can add up the same term. A constant can only add up or subtract with a constant. A variable term can only subtract or add up with the same variable term. (you can add or subtract x+x BUT not x²+x as both have different degree.)

Answer

$\large \boxed{ - 3x - 8}$

Answer 2

Answer:

$-3x - 8$

Step-by-step explanation:

The only thing you have to do is combine the like terms.

$-5-2x-3-x$          (combine the x values and the 5 and the 3)

$-3x-8$                       (That's all)

I'm not really sure what you did but I might have an idea. You might have subtracted the -5 and the -2x, but you cannot do that because they are not like terms and by that I mean that you have to subtract the -x from the -2x. The same goes for the -5 and -3 you have to keep those two together and subtract them. When you do that you will get -3x - 8.
