Question

ME AJUDEM POR FAVOR

Answer 1

Explicação passo-a-passo:

9)

$f(x) = \frac{x - 3}{2} \\ 0 = \frac{x - 3}{2} \\ \frac{x - 3}{2} = 0 \\ x - 3 = 0 \\ x = 0$

10)

$f(x) = \frac{ - 2x + 7}{3} \\ 0 = \frac{ - 2x + 7}{3} \\ \frac{ - 2x + 7}{3} = 0 \\ - 2x + 7 = 0 \\ - 2x = - 7 \: \: ( - 1) \\ x = \frac{7}{2}$
