Answer:
2) [tex]x - y = \frac{2}{3} [/tex]
[tex] = > x = \frac{2}{3} + y = \frac{2 + 3y}{3} [/tex]
3) [tex]3x + 2y = 6[/tex]
[tex] = > 3x = 6 - 2y [/tex]
[tex] = > x = \frac{6 - 2y}{3} [/tex]
4) [tex] \frac{1}{4} x + y = 2[/tex]
[tex] = > y = 2 - \frac{x}{4} = \frac{8 - x}{4} [/tex]
5) [tex]4x - 3y = - 33[/tex]
[tex] = > 3y = 4x + 33[/tex]
[tex] = > y = \frac{4x + 33}{3} [/tex]
