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.

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

zepdrix · Answer

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

zepdrix · Answer

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

zepdrix · Answer

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

zepdrix · Answer

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