368 - 3(x + 7) = 68
=> 3(x + 7) = 368 - 68
=> 3(x + 7) = 300
=> x + 7 = 300 : 3
=> x + 7 = 100
=> x = 100 - 7
=> x = 93
368-6.(x+7)=68
6.(x+7)=368-68

368 - 3 . ( x + 7 ) = 68
3 . ( x + 7 ) = 368 - 68
3 . ( x + 7 ) = 300
x + 7 = 300 : 3

x = 100 - 7
x = 93
368-3.(x+7)=68
\(3.\left(x+7\right)=368-68\)
\(3.\left(x+7\right)=300\)
\(x+7=300:3\)
\(x+7=100\)
\(x=100-7\)

k mik nha
368 - 3( x + 7 ) = 68
=> 3( x + 7 ) = 300
=> x + 7 = 100
=> x = 93
