[tex]1) \: x + 5 = 8 \\ x = 8 - 5 \\ x = 3[/tex]
[tex]2) \: 2x = 4 \\ x = \frac{4}{2} \\ x = 2[/tex]
[tex]3) \: \frac{x}{3} = 2 \\ x = 2 \times 3 \\ x = 6[/tex]
[tex]4) \: 0.2x = 1 \\ x = \frac{1}{0.2} \\ x = 5[/tex]
[tex]5) \: 3x + 6 = 12 \\ 3x = 12 - 6 \\ 3x = 6 \\ x = \frac{6}{3} \\ x = 2[/tex]
[tex]6) \: 3(x + 2) + 2 = 8 \\ 3x + 6 + 2 = 8 \\ 3x + 8 = 8 \\ 3x = 8 - 8 \\ 3x = 0 \\ x = \frac{0}{3} \\ x = 0[/tex]
