Your question seems to be -7 +(1/8) -(-9) + (1/2) but then there is a decimal in front of the next -2 so that makes no sense unless that is a period before starting a new equation. You can simply type this beginning section into a calculator to get your answer of (21/8), but I have a feeling you just tried to copy and paste a test question and it did not format correctly in your question so is probably much more complicated than using a calculator.
A better idea would be to write it in math terms instead of words, then find a common denominator so you can simplify. Writing it out in words makes it too hard for your brain to think about it in terms of math.
The domain is the set of inputs, in this case {-2, 0, 1, 3}
The range is the set of all possible outputs; here it's {-1, 3, 3.5}
Hope this helps.
Using the equation

, I found out that x is equal to -7.
The steps I took:

- Written out equation

- Distributive property on the left

- Subtracted 4x from both sides

- Subtraced 24 from both sides

- Divided by 2
