13-x = 13- x
theres is no answer for that x its a variable and 13 is a constant so is just 13-x
Ok, so first you solve whatever is in the parentheses.
(28 • 5-5 • 190)-2•228
28• 5 = 140
Then 5 •190 = 950
Then multiply 950 • 140 = 133,000
Then it should look like this:
133,000-2•228
Multiply 2 • 228 = 456
Then subtract 456 from 133,000.
The answer should come out to 132,544.
You can take the -1 times the final answer and keep the denominator as positive, or keep track of all the negatives.
