6 - (3x - 1) = 19
6 - 3x + 1 = 19
7 - 3x = 19
3x = -12
x = -(12/3)
x = -4

6-(3x-1)= 19
( => stands for it implies that )
=> 6-3x+1
=> 7-3x = 19
=> -3x = 12
=> x = 12/ (-3)
=> x = -4

6 - (3x - 1) = 19, remove parenthesis
6 - 3x + 1 = 19, add constants
7 - 3x = 19, leave x alone, move constant to the other side
7 -3x - 7 = 19 - 7, substract constants
-3x = 12, leave x alone, divide by constant
-3x/-3 = 12 / -3, divide
x = -4

6 - 1 (3x - 1) = 19
6 - 3x + 1 = 19
7 - 19 = 3x
3x = - 12
x = - 4

-(3x-1)=19-6
-3x+1=13
-3x=12
x=-4

6-(3x-1)=19
6-3x+1=19
7-19=3x
x=-12/3
x= -4
when it is written 6-(3x...
the numbers in the brackets are multiplied by -1
if it is 6+(3x...
then it is multiplied by 1
Hope this will help

6-(3x-1)=19
-(3x-1)=19-6=13
3x-1=-13
3x=-13+1=-12
x=-12/3
therefore x=-4

6 - (3x - 1) = 19
6 - 3x - 1 = 19
5-3x = 19 (colltect terms)
-3x = 14 (take 5 from both sides)
-x = 4.67 (3sf)
x = -4.67 (3sf)
I THINK this is ryt.
