First, you want to expand the brackets.
To do this you multiply everything inside the brackets by what comes before the bracket.
'2' x 'x' = 2x
2 x 3 = 6
Now write out the new equation
2x + 6 = 8
The next step is to balance the equation, whatever you do on one side, the same is done to the other.
To get rid of 6, we subtract 6
Therefore we must also subtract 6 from 8
8 - 6 = 2
The new equation is 2x = 2
Now we divide 2x by 2 to get 1x or x.
Again, we must do the same to the other side
2/2 = 1
x = 1
