Answer:

x = 1/6

Explanation:

1. Add and subtract the variable and the numbers.

So far: 4 - 3 = 9x - 3x

4 - 3 = 9x - 3x

2. Simplify.

4 - 3 = 1.

9x - 3x = 6x.

To do addition with variables, delete the variables, which now is 9 - 3, easy, 6, add the x back (only to the answer), so 6x.

Since 1 is on 1 part of the equal side, because 4 - 3 = 1.

And is 1 = 6x.

1/6 then is your final answer.
