Preaching to the choir, I had to take Algebra 9 three times before I finally passed [and even them it was probably more the result of pity]

I mean jez I took Typing thinking it was an easy credit and I could meet girls - here I am typing with one finger.

Are you still sure you want me helping with your homework?

He's looking for *suggestions *as to the answer.

Also, the answer is "You gotta show your work anyways".

You're asking for Algebra Homework help on a gaming forum?

Now by "Help" do you mean, "Give me the answer so I can start playing World of Tanks"?

Then the answer is no. You must do this yourself or else you'll never learn.

Either get a tutor, ask your teacher for help, or don't bother trying and fail just because you want to play tanks.

School first, games later.

Teacher: You cheated

Wewum: So?

Teacher: What's your source? Who helped you?

Wewum: World of Tanks forum.

Eh...?

Solve one of the equations in terms of x and sustitute that expression in both of the other equations. Then solve for y in one of the two other equations (the ones where you substituted your first expression) and substitute that expression in your last equation, leaving it only in terms of z.

Edit: As this probably made no sense whatsoever, here is a good video explaining how to do it: https://www.khanacademy.org/math/algebra/systems-of-eq-and-ineq/fancier-systems/v/systems-of-three-variables

1/ 5x-2y-5z = -1

2/ - x +2y-5z= -9

3/ -10x+4y+10z=-2

> the strategy is to reduce this to two equations in two unknowns... do that by eliminating one of the unknows for two pairs of equations.

I'll do that with equation 1 and 2 by adding the two equations together, thus eliminating the "y" calling this equation #4

4/ 4x - 10z = -10

> Next, well will eliminate another unknown from equations 1 and 2...

The further steps here; I got the ball rolling for you:

[sorry, as stated I entirely suck at math... that doesn't mean you should; I did the research - you learn the math. I'm doing my damnest to be helpful, while being clueless, without giving a wrong answer - not an easy task LOL]

Yep. Now we are doing quadruple line equations. Some kids start Algebra 1 in 6th grade BTW. xD And guys I figured it out BTW and thanks for the help Sgt_Sinful_needs. :D
