Question

Seis por (tres z mas uno) mas dieciocho es igual a 60?

Answer 1

Respuesta:

z = 2

Explicación paso a paso:

6(3z+1) + 18 = 60

18z + 6 + 18 = 60

18z = 60 - 24

18z = 36

z = 36/18

z = 2

Comprobación:

6((3*2)+1) + 18 = 60

6(6+1) + 18 = 60

6*7  +  18 = 60

42 + 18 = 60

Answer 2

6 (3z + 1) + 18 = 60

(18z + 6) + 18= 60

18z + 24 = 60

z = (60 - 24) ÷ 18

z = 36 ÷ 18

z = 2

Comprobación:

6 (3 × 2 + 1) = 6 (6 + 1) = 6 (7) = 42

42 + 18 = 60
