Answer 2

@zepdrix

Answer 3

does this have no restrictions

Answer 4

it's not written as an equation... there is no equals sign. Is that how it shows on your site, or did something not paste correctly?

Answer 5

i fixed it lol sorry

Answer 6

a (bx+2)=cx-12

I would start by multiplying out the left side:
abx + 2a = cx - 12

Then put all the x's on the left and the numbers on the right:
abx - cx = -2a - 12

Then factor out the x on the left:
x(ab - c) = -2a - 12

Answer 7

Finally, you could divide both sides by ab - c to solve for x:
x = (-2a - 12) / (ab - c)

There are restrictions... ab - c can't be equal to 0, since that would make the denominator equal 0... not allowed :)

Answer 8

No magic on this one... it was just simplifying and solving, then remembering that you can't divide by zero.

Answer 9

you could simplify it further though... could factor out a negative 2...

x = -2(a + 6) / (ab - c)

Answer 10

that rules out one of my answers then

Answer 11

some of your answers were based in magic?

Answer 12

huh

Answer 13

forget it, dumb joke.

Do your answers not include that last simplified expression for x?

Answer 14

this is what i got not sure if its right

Answer 15

that looks right... just different order on top than what I had... but same thing.

Answer 16

i agree with @JakeV8 .

Answer 17
