5x and 4x are "like words", meaning they the two have an x on them. (x^2 would not count quantity) so which you would be able to upload them. 5x + 4x = 9x So now you have 9x = 36 Divide the 36 by way of 9 and additionally you get 4. :)

Add your common terms first, 5x and 4x = 9x
Rewrite what you know,
9x = 36
To solve for x do the opposite of what is done to it originally (it's being multiplied, so divide)
x = 4
Sub back in to check your work
5(4) + 4(4)
20 + 16 = 36

1. 5x + 4x = 36
2. 5x + 4x = 9x
3. 9x = 36
4. 36 divided by 9 = 4
5. x = 4
2. 5x + 4x = 9x
3. 9x = 36
4. 36 divided by 9 = 4
5. x = 4

5x + 4x = 36 (add 5 and 4 together)
9x = 36 (divide by 9)
x = 4
9x = 36 (divide by 9)
x = 4
