X x 10 + X + X = 2016
X x ( 10 + 1 + 1 ) = 2016
X x 12 = 2016
X = 2016 / 12
X = 168 k mk , mk sẽ k lại bn
\(x\times10+x+x=2016\)
\(x\times10+x\times2=2016\)
\(x\times\left(10+2\right)=2016\)
\(x\times12=2016\)
\(x=2016:12\)
\(x=168\)

Xx10+Xx1+Xx1=2016
Xx(10+1+1)=2016
Xx12=2016
X=2016:12
X=168
Vậy=168
X x 10 + x + x = 2016
=> X x 13 = 2016
=> X = 155
đáp số x= 155
X x 10 + X + X = 2016
X x 10 + X x 1 + X x 1 = 2016
X x ( 10 + 1 + 1 ) = 2016
X x 12 = 2016
x = 2016 : 12
x = 168
x x 10 + x + x = 2016
x x 10 + x x 2 = 2016
x x (10 + 2) = 2016
x x 12 = 2016
x = 2016 : 12
x = 168
