Solve for x.

9x=5x+20

i thought i needed to do it like this
9x = 5x + 20
9x = x25
then divide both sides by 9
but idk i get a weird number and i have to put the answer in a box so i have no options.

9x=5x+20
Subtract 5X from both sides

4x=20
Now divide both sides by 4 so you only have x
x=5

REMEMBER: You do the same thing to both sides.

Hello! In order to solve this problem, you must subtract 5x from both sides to get 20 by itself. When you do that, you get 4x = 20. Now, divide each side by 4 to isolate the "x". When you do, you get x = 5. Your error had to have been that you added 5x into 20, but those numbers are not like terms. That's how you got an odd number. The answer is x = 5.
