Step-by-step explanation:
[tex] \frac{1}{2} x + 3 = - 1 \\ \frac{x}{3} + 3 = - 1 \\ \frac{x}{3} = - 1 - 3 \\ \frac{x}{3} = - 4 \\ x = - 4 \times 3 \\ x = - 12[/tex]
[tex] \frac{1}{2} x + 3 = - 1 \\ \frac{x}{2} + 3 = - 1 \\ \frac{x}{2} + 3 - 3 = - 1 - 3 \\ \frac{x}{2} = - 4 \\ \frac{x}{2} \times 2 = - 4 \times 2 \\ x = - 8[/tex]
