What is the value of x?

8x-9=3x+16

1. Bring all the values with an x to one side:

8x - 9 - 3x = 3x + 16 - 3x

=

5x - 9 = 16

2. Bring all the values without an x to the other side:

5x - 9 + 9 = 16 + 9

=

5x = 25

3. Divide both sides by 5 so that the x remains alone.

5x : 5 = 25 : 5

=

x = 5

The answer of the question is 5
