Answer:
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:)!!!
