air mengalir setiap detik nya 1 per 9 , jika mengalir 12 detik berapa hasil nya

n/3 - 3 = 12
*add 3 to both sides
n/3 - 3 + 3 = 12 + 3
n/3= 15
*multiply 3 to both sides
n/3 * 3 = 15 * 3
n = 45

3 n ​ − 3 = 12 n − 9 = 36 n = 45

To solve for n in the equation 3 n ​ − 3 = 12 , first add 3 to both sides to get 3 n ​ = 15 . Then multiply both sides by 3, resulting in n = 45 .

Jawaban:air mengalir 1 detik = [tex] \frac{1}{9} [/tex]Jika 12 detik maka[tex] \frac{1}{9} \times 12 = \frac{12}{9} \\ \\ sederhanakan \\ \frac{12}{9} \div 3 = \frac{4}{3} [/tex]Semoga membantu
