Question

five times the sum of a number and 3 is the same as 3 times the difference of twice the number and 1. what is the number

Answer 1

So 5(n+3) = 3(2n-1)
You distribute:
5n+15 = 6n-3
Subtract like terms:
-n = -18
Then divide by -1 to make the variable positive:
n = 18
5(18+3) = 3(2•18-1)
105 = 105
