Question

Resolva: (A+B) A= 4/2 - 1/2 B= 5/2- 4/2

Answer 1

Resposta:

(A + B) = 2

Explicação passo-a-passo:

Resolução:

$(A + B) = \frac{4}{2} - \frac{1}{2} + ( \frac{5}{2} - \frac{4}{2} ) \\ (A + B) = \frac{4 - 1}{2} + \frac{5 - 4}{2} \\ (A + B) = \frac{3}{2} + \frac{1}{2} \\ (A + B) = \frac{3 + 1}{2} \\ (A + B) = \frac{4}{2} \\ (A + B) = 2$
