Help! FAN, MEDAL AND MY HEARRTTT

OpenStudy (pflori1234_pop):

The product of two numbers is 65 their difference is 8. Solve and show work

OpenStudy (adamaero):

Turn those words into variables! 65 = a + b 8 = a/b

OpenStudy (adamaero):

Did I do something wrong for the first expression though? (Hint: I did.)

OpenStudy (pflori1234_pop):

yea u have to swith them

OpenStudy (pflori1234_pop):

8 = a - b 65= a/b

OpenStudy (pflori1234_pop):

and switch the sign to minus

OpenStudy (adamaero):

um, nope What does taking a product of two numbers mean?

OpenStudy (hidden14):

Well if - is difference, and + is sum, what would words for * and / be?

OpenStudy (danjs):

a*b -- product a/b -- ratio

OpenStudy (adamaero):

aw come on DanJS are you doing the learning or is the OP? (I think neither!)

OpenStudy (pflori1234_pop):

i need to solve it -.-

OpenStudy (pflori1234_pop):

oh sorry i meant 8 = a - b 65= a*b

OpenStudy (pflori1234_pop):

now im confused how to solve

OpenStudy (pflori1234_pop):

@adamaero

OpenStudy (pflori1234_pop):

anyone?

OpenStudy (pflori1234_pop):

@DanJS

OpenStudy (triciaal):

product is what you get when you multiply

OpenStudy (danjs):

yeah you have the two equations correct a - b = 8 a * b = 65 to solve that for 'a' and 'b', you can substitute, solve one of them for a or b, then use that in the other equation

OpenStudy (triciaal):

difference is what you get when you subtract

OpenStudy (danjs):

a - b = 8 solving for a , a = 8 + b use that for 'a' in the second equation a*b=65 (8+b) * b = 65

OpenStudy (triciaal):

agree with @DanJS's process
