5X - 4 = 2X + 6
subtract 2X from each side
5X - 2X - 4 = 2X - 2X + 6
3X - 4 = 6
add 4 to both sides
3X - 4 + 4 = 6 + 4
3X = 10
divide both sides integers by 3
(3/3)X = 10/3
X = 10/3
==========check in original equation
5(10/3) - 4 = 2(10/3) + 6
50/3 - 4 = 20/3 + 6
Now, fraction manipulation comes in handy here
you should know, - 4 = - 12/3 and 6 = 18/3, so
50/3 - 12/3 = 20/3 + 18/3
38/3 = 38/3
==========checks and is a good fraction exercise
