"The product of 4 and a number" translates to what algebraic expression?

OpenStudy (theedwardsfamily):

4*n? @jim_thompson5910

correct, you multiply

jimthompson5910 (jim_thompson5910):

"18 more than twice the number" translates into what expression?

OpenStudy (theedwardsfamily):

18+2x?

jimthompson5910 (jim_thompson5910):

it's a good idea to use the same variable

jimthompson5910 (jim_thompson5910):

but you have the right idea

OpenStudy (theedwardsfamily):

oh. 18+2n

jimthompson5910 (jim_thompson5910):

the entire sentence "The product of 4 and a number is 18 more than twice the number." translates to 4n = 18 + 2n

jimthompson5910 (jim_thompson5910):

to find the unknown number, you need to solve 4n = 18 + 2n for n
