Question

(_)×(-2)×(+4) = -32

(-3)×(-6)×(_) = +18

(+5)×(_)×(+3) = -45

(-4)×(+5)×(-3) = _​

Answer 1

Resposta:

(_)×(-2)×(+4) = -32

$x \times ( - 2) \times 4 = - 32 \\ - 8x = - 32 \times ( - 1) \\ 8x = 32 \div (8) \\ x = 4$

(-3)×(-6)×(_) = +18

$- 3 \times ( - 6) \times x = 18 \\ 18x = 18 \div (18) \\ x = 1$

(+5)×(_)×(+3) = -45

$5 \times x \times 3 = - 45 \\ 15x = - 45 \div (15) \\ = - 3$

(-4)×(+5)×(-3) = _

$- 4 \times 5 \times ( - 3) \\ - 20 \times ( - 3) \\ = 60$
