3(2x-1) = 7
6x-3= 7
6x= 10
x = 10/6 or 5/3.

3(2x-1)=7
Distrubute (multiply the 3 over both terms in ())
6x-3=7
Simplify (add 3 to both sides)
6x=10
Simplify (divide both sides by 6)
x=10/6
Simplify terms
x=5/3
Double check your work
3(2(5/3)-1)=7?
3(10/3-1)=7?
10-3=7?
7=7
x=5/3

multiply the 3 to both the 2x and the 1 and you get 6x - 3 = 7
then add the 3 to both sides and get 6x = 10 then divide by 6 and get x = 10/6 which = 5/3

First multiply 3 by 2x
Then multiply 3 by -1
You should get 6x -3=7
Add 3 to the 7 and divide by 6. What do you get? I don't want to give you the complete answer, because then you won't be learning anything.

3(2x - 1) = 7
3*2x - 3*1 = 7
6x - 3 = 7
6x -3 +3 = 7 + 3
6x = 10
6x / 6 = 10 / 6
x = (10/2) / (6/2)
x = 5 / 3
x = 1.6667
