2681 - x : 11 = 2543
=> x : 11 = 2681 - 2543
=> x : 11 = 138
=> x = 138 x 11
=> x = 1518
vậy_____
x:11=2681-2543
x:11=138
x=138x11
x=1518
\(2681-x\div11=2543\)
\(x\div11=2681-2543\)
\(x\div11=138\)
\(x\) \(=138\times11\)
\(x\) \(=1518\)
x:11=2681-2543
x:11=138
x=138 x11
x=1518
k nhé
2681 - x : 11 = 2543
x : 11 = 2681 - 2543 = 138
x = 138 x 11 = 1518
2681 - x : 11 = 2543
=> x : 11 = 2681 - 2543
=> x : 11 = 138
=> x = 138 x 11
=> x = 1518
Vậy x = 1518
