x=4 
4x-(12÷3)+2x=20
4x-(4)+2x=20
4x4-4+2x4=20
16-4+8=20
12+8=20
4x - ( 12 ÷ 3 ) + 2x = 20
4x - 4 + 2x = 20            Always begin with subtraction or multiplication first 
4x + 2x - 4 = 20            Combine term 
6x - 4 = 20                    Add 4 for each side 
6x = 24                          Divide by 6 fro both side 
x = 4
