Best ResponseYou've already chosen the best response.1I know that answer is (11, 1/2) but I don't know how to solve it.

Best ResponseYou've already chosen the best response.1So, you know what y equals. If you see y in another equation can't you just plug it in?

Best ResponseYou've already chosen the best response.1What I meant is that, someone told me the answer, but not how they got it. Could you explain to me how they would have got (11, 1/2) as the answer?

Best ResponseYou've already chosen the best response.1I will ask you a series of questions to help you solve this. Question 1: what does y equal?

Best ResponseYou've already chosen the best response.1Y does not equal 1/2 Read the first equation out loud and listen to what y is equal to.

Best ResponseYou've already chosen the best response.1If x = 25r + 25b Then x is equal twentyfive r plus twentyfive b.

Best ResponseYou've already chosen the best response.1Y = 1/2X  6 There is no other answer. By writing y=1/2x6 We say Y is equal to one half of x minus 6. There is nothing else that is the answer.

Best ResponseYou've already chosen the best response.1Question 2: If x = 5, what is y , if: x + 10 = y

Best ResponseYou've already chosen the best response.1This is the substitution part, if you know that x is 5..... What is y?

Best ResponseYou've already chosen the best response.1Y would then be x+10=y 5+10=y 15=y

Best ResponseYou've already chosen the best response.1Now that's just a basic use of substitution. Let's go back to your problem(s) You know what y is equal to y=1/2x6 So then you look at the other equation 2x + 6y = 19 and say Well if i know what y is, I can replace it with the y there. So 2x + 6y = 19 turns into 2x + 6(1/2x  6) = 19

Best ResponseYou've already chosen the best response.1So there's the way to solve for x. Once you get a numerical answer for x, you can solve for y.

Best ResponseYou've already chosen the best response.1Did you solve for x?

Best ResponseYou've already chosen the best response.1Well, what I meant was do i combine 2x and 1/2x?

Best ResponseYou've already chosen the best response.1You need to distribute the 6 since it was 6y and then you can proceed with solving for x from there.

Best ResponseYou've already chosen the best response.15x  36 = 19 5x = 55 x = 11 Replace x in one of the equations. y = 1/2(11)  6 y = 5.5  6 y = 1/2

Best ResponseYou've already chosen the best response.1And you have just solved by substitution.

Best ResponseYou've already chosen the best response.1How do you go from 2x + 6(1/2x  6) = 19 to 5x  36 = 19?

Best ResponseYou've already chosen the best response.16 times 1/2x equals 3x and 6 times 6 equals 36 You may need to go back and review some algebra. It would help tremendously and I do not see another way for you to continue in mathematics without it.

Best ResponseYou've already chosen the best response.1I've done the other problems myself, its just that i didn't understand this one.

Best ResponseYou've already chosen the best response.1Distribution property is one of the earliest rules learned in algebra. If you can get from 2x + 6(1/2x6) = 19 to 5x36=19 well then there may be some necessary review:
