How would i go about solving this complex fraction?

[(x/3)-4] / [5+(1x)]

(1x) ?

That is supposed to be 1/x sorry!

multiply numerator and denominator by 3x

I am unsure what you mean by "solve", there is no equal sign. Do you mean "simplify"?

To solve this complex fraction, you can follow these steps:

Step 1: Simplify the numerator
To simplify the numerator, you can apply the distributive property by multiplying -4 with both terms inside the bracket:
[(x/3) - 4] = (x/3) - 4

Note: The brackets [] are not essential in this case since there is only one term in the numerator, but they help visualize the expression.

Step 2: Simplify the denominator
The denominator is 5 + (1 * x) or simply x + 5.

Step 3: Combine the simplified numerator and denominator
Now that the numerator is simplified to (x/3) - 4 and the denominator is x + 5, you can write the complex fraction as:
[(x/3) - 4] / (x + 5)

This is your simplified complex fraction.
