The "plus x minus two x" part basically means "minus x".
So, "six minux x equals five".
This means that six minus five is x. So, x is one!
Now, let's check this in the problem: replace x with 1. Six plus one minus two ones equals five? Yes, it does!
The answer is x=1.
Answer:
x > -2y + 8
Step-by-step explanation:
$50 each
(2 books + 1 book : $100 + $50 = $150)
10(2x)+x
21x is the original number
12x is the reversed number
24x is the reversed then doubled number
Set up an equation:
24x=21x+9
3x=9
x=3
The original number is 63 and the reversed number is 36, which then is 72 when doubled.
