25+3(x-8)=106
3(x-8)=106-25
3(x-8)=81
x-8 = 81 : 3
x-8 = 27
x = 27 + 8
x = 35
\(25+3\left(x-8\right)=106\)
\(3\left(x-8\right)=106-25\)
\(3\left(x-8\right)=81\)
\(\left(x-8\right)=81
:

\(x-8=27\)
\(x\) \(=27+8\)
\(x\) \(=35\)
25+3.(x-8)=106
3.(x-8)=106-25
3.(x-8)=81
x-8=81:3
x-8=27
x =27+8
x =35
vậy x =35
25+3(x-8)=106
3(x-8)=106-25
3(x-8)=81
x-8 = 81 : 3
x-8 = 27
x = 27 + 8
x = 35
