Resposta:

$8$

Explicação passo-a-passo:

$- ( - 2) \times 3 + ( - 1) \times 2 + ( - 3) \times 2 - ( - 2) \times 5 \\ 2 \times 3 + ( - 1) \times 2 + ( - 3) \times 2 - ( - 2) \times 5 \\ 2 \times 3 + ( - 1) \times 2 + ( - 3) \times 2 + 2 \times \\ 2 \times 3 + ( - 1) \times 2 - 3 \times 2 + 2 \times 5 \\ - (1 \times 2) \\ - 2 \\ 2 \times 3 - 2 - 3 \times 2 + 2 \times 5 \\ 2 \times 3 - 2 - 3 \times 2 + 10 \\ - 2 + 10 \\ + (10 - 2) \\ 8$
