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)=25-106
3.(x-8)=-81
x-8=-81:3
x-8=-27
x=-27+8
x=-19
25 - 3 . ( x - 8 ) = 106
3 . ( x - 8 ) = 25 - 106 = -81
x - 8 = ( -81 ) : 3 = -27
x = ( -27 ) + 8 = -19
Vậy x = -19

a. 25 + 3(x-8) = 106
3(x-8) = 106 - 25 = 81
x -8 = 81 : 3 = 27
x = 27 +8 = 35
b. 32(x +4) - 52 = 5.52
9(x+4) - 25 = 5.25 = 125
9(x+4) = 125 + 25 = 150(Đề sai)

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

25+3.(x-8)=106 =>3x-3.8=106-25
3x-24=81
3x=81+24
3x=105
x=105:3
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
