i know this because if it tells me that X = 1 and it shows -x+7 then i know it will be 6. Have a Great Day!
Answer:
x = -1
Step-by-step explanation:
5 less than a number is equivalent to 1 more than three times the number
number = x
x - 5 = 3x + 1
now im going to get the numbers and variable on different sides
x - 5 + 5 = x
3x + 1 - 3x = 1
x + 3x = 4x
1 - 5 = -4
4x = -4
lastly im going to divide each side by 4
4x / 4 = x
-4 / 4 = -1
x = -1

I believe you can do x + 2.7 = 16.
I took geometry last year and those arrow things are basically saying the line is the same if they have the same number of arrows. Using that logic, you can equal them out and find X.
Your answer is 16 - 2.7
(13.3)
