3(x+10) + 4(x+20) +5x + 185 - 3x?

Question

THANK YOU

Answer 1

you first have to distribute everything:

3x+30+4x+80+5x+185-3x

then you add all the variables together and the numbers together:

3x+4x+5x-3x+30+80+185=9x+295

then you get:

9x+295

then if you want to get the value of x, you put 9x and 295 on the different side of a equation:

9x= - 295

then to get x alone, you divide -295 by 9:

x =  - 32.78 or - 295/9

Answer 2

PEMDAS

Distribute first what you can [the 3(x+10) and the 4(x+20)

so it becomes...

3x + 30 + 4x + 80 + 5 x + 185 - 3x

Then combine like terms (the x's and the whole numbers separate)

(i'm putting it in order first) so take >>> 3x - 3x + 4x 5x + 30 + 80 + 185

[ 3x - 3x + 4x 5x ]+ [30 + 80 + 185]

so it becomes [9x] + [295]

9x + 295

if you're solving for x then set the equation equal to zero

9x + 295 = 0

Bring the 295 over

9x = - 295

divide 9 to get x alone

answer: x = -295/9

Answer 3

Probably

3(x+10) + 4(x+20) +5x + 185 - 3x=0

3x+30+4x+80+5x+185-3x=0

12x+295-3x=0

9x+295=0

9x=-295

x=-32.77
