(LONGEST EQUATION EVER) 3x+4(x-8+2-3x+6x-8+2(x+7)=12x-5(x+1)-7x+8(x-2)+9x-20x+6-1=?

Question

I NEED to know this, Algebra teacher asked me and i'd like to prove him i can do it :P

Answer 1

me thank yu forgot a ")", so me added 1 after "-8"

left side:3x+4(x-8+2-3x+6x-8)+2(x+7)

become 3x+4(4x-14)=3x+16x-56

=19x-56

--------- rite side:12x-5(x+1)-7x +8(x-2)+9x-20x+6-1

become 12x-5x-5-7x+8x-16+9x-20x+6-1

=x(12+8+9-5-7) +(-5 -16 -20 -1 +6)

=17x -36

thus 19x-56=17x-36

2x=56-36=20

x=10

Answer 2

Well if you try to put it in a simple way, the equation is most likely yet to be quite simple.

 

3=4 as well as x=8 as a simple version it is most likely to become as this problem:

 

(x+y)= 3+4, 8* + (x-(sum) )) 12x

Answer 3

it is impossible there is no stop in the first part of the first part of the equal sign so the answer is unidentifiable or unidentified

Answer 4

i think it might be 96719. i dont really know if it is actually the real answer because i did it on a calculator.

Answer 5

My closest answer is "x=0.2682926829"

JUSTIN BIEBER >3 :)

Answer 11

x=69

Answer 12

the answer is 2/5

took me 45 seconds to solve and im terrible at math

Answer 13

unsimplified answer: - 38/30

simplified answer: -1 4/15

Explanation

3x+4(x-8+2-3x+6x-8+2(x+7)=12x-5(x+1)-7x+8(x-2)+9x-20x+6-1

first,distribute the 2(x+7)

3x+4(x-8+2-3x+6x-8+2x+14)=12x-5(x+1)-7x+8(x-2)+9x-20x+6-1

second, distribute all

3x+4x-32+8-12x+24x-32+8x+56=12x-5x+5-7x+8x-16+9x-20x+6-1

next,combine like terms

27x+32=-3x-6

then, isolate x but allow for a coefficient on x

38=-30x

finally,completely isolate x 

x= - 38/30

simplify if needed.

Answer 19

Let's solve your equation step-by-step.

3x+4(x−8+2−3x+6x−8+2(x+7))=12x−5(x+1)−7x+8(x−2)+9x−20x+6−1

Step 1: Simplify both sides of the equation.

3x+4(x−8+2−3x+6x−8+2(x+7))=12x−5(x+1)−7x+8(x−2)+9x−20x+6−1

Simplify: (Show steps)

27x=−3x−16

Step 2: Add 3x to both sides.

27x+3x=−3x−16+3x

30x=−16

Step 3: Divide both sides by 30.

30x
