Answer:

x = 6

Explanation:

20 = 7x + 2 - 4x

7x + 2 - 4x = 20 (switch the sides)

7x - 4x + 2 = 20 (group the like terms together)

3x + 2 = 20 (add similar numbers, in this case it's the both x's)

-2 -2 (subtract 2 on both sides)

------------------

3x = 18

/3 /3 (divide both sides by 3)

-------------------

x = 6
