Hello Guest!
Equation method
I \(x - 2y + 3z = 2\ |\ Change\ of\ sign\ when\ changing\ page\\ x=2+2y-3z\)
II \(2x - 3y + 8z = 7\ |\ Change\ of\ sign\ when\ changing\ page\\ 2x=7+3y-8z\ |\ divided\ on\ both\ sides\ by\ 2\)
\(x=3.5+1.5y-4z\)
III \(3x - 4y + 13z = 8\ |\ change\ of\ sign\ when\ changing\ page\\ 3x=8+4y-13z\ |\ divided\ on\ both\ sides\ by\ 3 \)
\(x=\frac{8}{3}+\frac{4}{3}y-\frac{13}{3}z\)
I = II \(2+2y-3z=3.5+1.5y-4z\ |\ change\ of\ sign\ when\ changing\ page\\ z=1.5-0.5y\)
II = III \(3.5+1.5y-4z=\frac{8}{3}+\frac{4}{3}y-\frac{13}{3}z\)
