7x + 2 = 30

First, subtract 2 from both sides:

7x + 2 (-2) = 30 (-2)

7x = 30 - 2

7x = 28

Next, divide 7 from both sides:

(7x)/7 = (28)/7

x = 28/7

x = 4

x = 4 is your answer.

First subtract the 2 to isolate the 7x. Remember what you do to one side you do to the other, so then you would subtract 2 from 30 as well giving you 7x=28. After that in order to isolate x, you would divide by 7 on both sides giving you x=4.
