Solve the system by elimination. Can you show all the steps please???

Question

anonymous · Answer

do you got an example I can show you on?

anonymous · Answer

$$-2x + 2y + 3z = 0$$
-2x - y +z = -3
2x + 3y + 3z = 5

anonymous · Answer

here all you need to do is isolate x or y.

anonymous · Answer

how did you get that?

anonymous · Answer

what you do to one side you must do to another, understand?

anonymous · Answer

What is the slope of the line x = -5?

anonymous · Answer

You have to isolate the variable and y and z? you have a different function then, Let me see it and I'll explain better ok

anonymous · Answer

Do you have a problem to go with it or a graph?

anonymous · Answer

its not a graph problem it is what i posted.

anonymous · Answer

solve the system by elimination.
−2x+2y+3z=0
-2x - y +z = -3 
2x + 3y + 3z = 5
(this is how it is asked)

anonymous · Answer

ok nvm i got it figured out my dad helped me thanks anyways!

anonymous · Answer

oh ok :) notice you need to avoid one variable by adding or subtracting 2 equations and solving the resulting pair of equations with 2 variables

anonymous · Answer

−2x+2y+3z=0 (this is 1)
 -2x - y +z = -3 (this is 2)
2x + 3y + 3z = 5 (this is 3)

anonymous · Answer

you need to subtract the the sencond one from the first one to get x, do you know how to do that?
