First, you would distribute 9 equally to x and 4. The problem now is 9x + 36- 4x. Next, you turn the - into a + and make it negative so there is only addition. The problem is now 9x + 36 + (-4). You would now add 36 + (-4). Which is 32. The problem is now 9x =32. Now, divide 9 by 32 to get your answer, 3.5.
Hope this helps:)
