Answer:
x = 9
Step-by-step explanation:
Step 1: Write equation
-4 - x = -13
Step 2: Solve for <em>x</em>
<u>Add 4 to both sides:</u> -x = -9
<u>Divide both sides by -1:</u> x = 9
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-4 - 9 = -13
-13 = -13
Correct answer is the second sentence, the expression is worth 4 times as much as (85 + 123)
