## anonymous one year ago Systems of Equations, please help =) Solve without matrix 5x-y+z=4; x+2y-2=5; 2x+3y-3=5 I have the answer, but have tried multiple time and cannot get it.

1. zepdrix

System of three equations? :( Oh boy these are not fun lol

2. zepdrix

Oh two of them only involve x and y! yay! :)

3. zepdrix

Start there, with the x/y equations, find a solution for x or y.

4. zepdrix

$\large\rm x+2y-2=5$$\large\rm 2x+3y-3=5$Let's get these into standard form: In which only x's and y's appear on the left sides of the equations.

5. zepdrix

So we'll add 2, and 3, respectively, ya?$\large\rm x+2y=7$$\large\rm 2x+3y=8$Ok with that step? :o

Yes. Thank you! So sorry I got distracted.
