Jose sold half of his comic books and then bought twenty more. he now has 30. with how many did he begin?

1) Jose started with x amount of comic books, then sold half:

(x÷2)

2) Then Jose bought twenty more:

+20

Now Jose has 30:

=30

Therefor, your equation is going to be (x÷2) + 20 = 30

Now you solve it for x:

Step 1) subtract 20 from both sides

(x÷2) + 20 - 20 = 30 - 20

Step 2) read as 'x over 2' or 'x divided by 2'

x÷2 = 10

Step 3) multiple by 2 on both sides to cancel out the 2 in 'x over 2'

x÷2 * 2 = 10 * 2

Step 4)

x=20

* Thus, your answer is x = 20

* Hopefully this helps:) Mark me the brainliest:)!!!
