25+3*(x-8)=106
\(\Rightarrow\)3*x-3*8=106-25
\(\Rightarrow\)3*x-24=81
\(\Rightarrow\)3*x=81-24
\(\Rightarrow\)3*x=57
\(\Rightarrow\)x=57:3
\(\Rightarrow\)x=19
25 + 3*(x-8) = 106
3*(x-8) = 106 - 25 = 81
x - 8 = 81 : 3 = 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
