b) - 5

c) - 9

d) - 4

e) $\frac{3}{2}$

f) 3

g) $\frac{3}{4}$

h) $\frac{3}{7}$

Explicação passo a passo:

a) x + 4 = 0 → x = - 4

b) x + 5 = 0 → x = - 5

c) x + 9 = 0 → x = - 9

d) x + 4 = 0 → x = - 4

e) 2x - 3 = 0 → 2x = 3 → x = $\frac{3}{2}$

f) 2x - 6 = 0 → 2x = 6 → x = $\frac{6}{2} = \frac{3}{1}$ = 3

g) 4x - 3 = 0 → 4x = 3 → x = $\frac{3}{4}$

h) 7x - 3 = 0 → 7x = 3 → x = $\frac{3}{7}$
