\(2536:14=174\)

2436/x=12

x= 2436/12

x=203

\(2436:x=12\)

\(\Rightarrow x=2436:12\)

\(\Rightarrow x=203\)

^_^^_^^_^

2436:x=12

        x=2436:12

        x=203

y=1227

(y + 2436) : 9 = 407

y + 2436 = 407. 9

y + 2436 =      3663

y            = 3663 - 2436

y            =         1227

vay y = 1227

y = 1227

24 36   -   6 12   =   2 3   -   1 2   =   4 6   -   3 6   =   1 6

12836-x=2436:6

=>12836-x=406

=>x=12836-406=12430

\(2436\cdot\left(5\cdot x+103\right)=12\)

\(5\cdot x+103=2436:12=203\)

\(5\cdot x=203-103=100\)

\(x=100:5=20\)

\(2436.\left(5x+103\right)=12\)

\(5x+103=12:2436\)

\(5x+103=12:2436\)

\(5x+103=\frac{1}{2003}\)

\(5x=\frac{1}{2003}-103\)

\(5x=\frac{-206308}{2003}\)

\(x=\frac{-206308}{2003}.\frac{1}{5}\)

\(x=\frac{-206308}{10015}\)

\(2436\times\left(5\times x+103\right)=12\)

\(\Rightarrow5\times x+103=12:2436\)

\(\Rightarrow5\times x+103=\frac{1}{203}\)

\(\Rightarrow5\times x=\frac{1}{203}-103\)

\(\Rightarrow5\times x=-\frac{20908}{203}\)

\(\Rightarrow x=-\frac{20908}{203}:5\)

\(\Rightarrow x=...\)

Bn tự tính nha !

Hok tốt #

2685:4=671(dư 1)

1684:2=842

2436:6=406

2415:3=805

2685 : 4 = 671 (dư 1)

1684 : 2 = 842

2436 : 6 = 406

2415 : 3 = 805

2685 : 4 = 671 (dư 1)

1684 : 2= 842

2436 : 6 = 406

2415 : 3 = 805

Ta có: 2436 : x = 12

x = 2436 : 12

x = 203

Vậy x = 203
