if u intended to type this equation as [tex]3y+5\frac{x}{z}=-2[/tex]
[tex]3y+5\frac{x}{z}=-2[/tex]
[tex]3y=-2-5\frac{x}{z}[/tex]
then [tex]y=-\frac{2}{3} -\frac{5x}{3z}[/tex]
but if you actually typed it as [tex]3y+5\frac{x}{z}+-2[/tex]
[tex]3y+5\frac{x}{z}+-2=0[/tex]
[tex]3y+5\frac{x}{z}-2=0[/tex]
[tex]3y+5\frac{x}{z}=2[/tex]
[tex]3y=2-5\frac{x}{z}[/tex]
then [tex]y=\frac{2}{3} -\frac{5x}{3z}\\[/tex]
