5

Answer 4

8x - 9 = 3x + 16

First, add 9. This is because we need to perform the opposite operation.

8x = 3x + 25

Now, we need to subtract 3x. We subtract 3x as a whole because x is sought to be apart of the unit "3." Normally, we would divide by 3, but since we're not isolating x and simply carrying it over, we can subtract.

5x = 25

Now you simply divide as a last step since x has been isolated with it's coefficient.

Answer 5

Yeah then you divide both sides by 5 and 5x/5 cancels out and 25/5 = 5 So
x=5
