Answer 4

Whenever you see these types of problems, You always remember that ok in order to get for example 30 i need subtract something side to side like 20

So for this problem it's really simple
Take your equation :
2x + 20 = 30
(Knowing that 2x +20 is not equal to 30)
Take 20 from each side
2x - 20
and
30 - 20 = 10

So 2x = 10 over x= 10/2 * 2 go's into 10 5 times)

So your answer will be : X=5

Hope this helped !
