SIMPLIFY (-8x)-5m+3m-7x-(-3x)+m?

Question

Could you please explain it step by step, I don't understand it.

Thanks

Answer 1

-12x - m

You just have to combine the like terms

Answer 2

(-8x)-5m+3m-7x-(-3x)+m

= (-8x) - 2m - 7x - (-3x) + m

= (-15x) - 2m - (-3x) + m

= (-15 + 3)x - 2m + m

= (-12x) - m

Answer 3

Take it one step at a time, combining like terms, becareful of the neg and pos signs.

-8x -5m + 3m -7x + 3x +m

the first ( ) are not needed, the ( ) negative of a negative is positive

combine like terms

- 8x - 7x + 3x - 5m + 3m + m

add like terms together

(-8-7+3)x or 12x    (-5+3+1) m  or  -m

answer  12x-m

Answer 4

(-8x) - 5m + 3m - 7x - (-3x) + m (subtracting a negative means adding a positive, so change -(-3x) to + 3x)

-8x - 5m + 3m - 7x + 3x + m (group like terms)

(-8x - 7x + 3x) + (3m - 5m + m) (combine like terms)

-12x - m <===ANSWER

*You are free to skip the "group like terms" step. I just added that step to help you understand it better. Remember that like terms are constants or variables with the same power (exponent).

Answer 5

You have to combine the "like terms" this means combine the terms with an x together and combine those with an m together.

First combine the x's: -8x - 7x - (-3x) = -8x - 7x + 3x = -15x + 3x = -12x

Now combine the m's: -5m + 3m + m = -5m + 4m = -m

So the whole expression simplifies to: -12x - m

Hope this helps!

Answer 6

(-8x)-5m+3m-7x-(-3x)+m =

(final answer) : (-12x)-1m

Answer 7

5a(b+3d) = !!?????????????!!!!!!!?????????????

Answer 8

I'm confused with your (-8x),are u sure it has close and open parenthesis. it may vary actually...

option 1 solution:

~regroup variables of x and m

(-8x)-7x-(-3x)-5m+3m+m=N

(-8x)-7x+3x-5m+3m+m=N

-15x+3x-m=N

-12x-m=N

or

option 2 solution

(-8x)-7x-(-3x)-5m+3m+m=N

if you infer that (-8x) is multiplication...use distributive property

(-8x)-7x+3x-5m+3m+m=N

(-8x)-4x-m=N

32x2 -8xm=N

32x squared - 8xm=N

~N means answer
