# Another equation problem

My teacher is a prick and I have not been to school in almost 17 years. I couldn't find the answer on Google or Wolfram, so I was hoping the more mathematically inclined could help me :

-19 = 3 + 4x they want the answer "simplified" as much as possible.

Damn, I always hated math. I was never any good at it.

#1They want to know what the x stands for, in other words x=

-19 - 3 = 4x

which is the same as

-22 = 4x

then isolate x by dividing each side by 4

-22/4 = x

so x = -11/2 or -5.5

In general, everything done to the left hand side (of =) has to be done to the right hand side.

To check that it has been done properly, plug the solution back in:

-19 = 3 + 4x

where x = -5.5

so

-19 = 3 + (4 * -5.5)

-19 = 3 + (-22)

-19 = 3 - 22

which is true, so the answer is right.

#4Thanks but what does the x stand for ? 5.5. ?

#5So, the answer is x= -5.5 ? Is that right ?

#9if you need to brush up on your algebra skills, start with the simplest basics with an equation that has even numbers and no negatives. Then everything will make more sense after that. like:

2x + 4 = 24 answer x = 10

then move up to :

2x + 4 = 25 answer x = 10.5

#10Thanks for the help guys. I appreciate it.
