Help Idk what I did wrong show your work please

x = 10

Step-by-step explanation:

first Add 20 to both sides.

4x = x + 10 + 20

Then Simplify x + 10 + 20 to x + 30

4x = x + 30

Then u subtract x from both sides

4x - x = 30

Simplify 4x - x to 3x

3x = 30

Then u divide both sides by three

x = 30/3

Then u last simplify 30/3 to 10

x = 10
