Explicación paso a paso:

1)

A)

[tex]4x + 3 = 15 \\ 4x = 15 - 3 \\ 4x = 12 \\ x = 12 \div 4 \\ x = 3[/tex]

B)

[tex] - 2x - 6 = 10 \\ - 2x = 10 + 6 \\ - 2x = 16 \\ x = 16 \div - 2 \\ x = - 8[/tex]

C)

[tex] \frac{x}{10} - 8 = 4 \\ \frac{1}{10} x = 4 + 8 \\ \frac{1}{10} x = 12 \\ x = 12 \times 10 \\ x = 120[/tex]

2)

A)

[tex]2x + 1 = 5 \\ 2x = 5 - 1 \\ 2x = 4 \\ x = 4 \div 2 \\ x = 2[/tex]

B)

[tex] - x - 8 = 6 \\ - x = 6 + 8 \\ - x = 14 \\ x = 14 \div - 1 \\ x = - 14[/tex]

C)

[tex] \frac{2x}{15} - 4 = - 8 \\ \frac{2}{15} x = - 8 + 4 \\ \frac{2}{15} x = - 4 \\ x = - 4 \times \frac{15}{2} \\ x = - 30[/tex]

D)

[tex] \frac{x}{2} - 3 = 4 \\ \frac{1}{2}x = 4 + 3 \\ \frac{1}{2} x = 7 \\ x = 7 \times 2 \\ x = 14[/tex]
