Question 583710: Please help me solve this word problem I don't understand it! Thank you so much.
I am thinking of a number I multiply it by 7 and add 1. I get the same answer if I multiply by 2 and add 161. What is my number?

let n = "the number"
:
Just write an equation for what it says:
"multiply it by 7 and add 1. I get the same answer if I multiply by 2 and add 161. "
7n + 1 = 2n + 161
7n - 2n = 161 - 1
5n = 160
n = 160/5
n = 32
:
Prove this to yourself, substitute 32 for n in the original equation
:
Not that hard to understand, is it!
