[(12×n+3)×4-6]:9=150​

Răspuns :

Explicație pas cu pas:

[ ( 12 × n + 3 ) × 4 - 6 ] : 9 = 150

( 12 × n + 3 ) × 4 - 6 = 150 × 9

( 12 × n + 3 ) × 4 - 6 = 1350

( 12 × n + 3 ) × 4 = 1350 + 6

( 12 × n + 3 ) × 4 = 1356

12 × n + 3 = 1356 : 4

12 × n + 3 = 339

12 × n = 339 - 3

12 × n = 336

n = 336 : 12

n = 28

(12×n+3)×4-6=150×9

(12×n+3)×4-6=1350

(12×n+3)×4=1350+6

(12×n+3)×4=1356

12×n+3=1356:4

12×n+3=339

12×n=339-3

12×n=336

n=336:12

n=28
