Best ResponseYou've already chosen the best response.1Expand the brackets. What do you get? Then, collect like terms. I'll give you a similar example. 4(xy) + (x2y) = 4x  4y + x  2y = 4x + x  4y  2y = 5x  6y Try using a similar approach for your question

Best ResponseYou've already chosen the best response.0to expand the brackets and to distribute means the same thing. multiply the term outside by each term inside follow the example given by @ Tommynaut above

Best ResponseYou've already chosen the best response.1You can add and subtract letters (also known as pronumerals or variables) that are the same. For example, I can't do anything with x + 2y, because the letters are different! How about 2x + 3x? The letters are the same! So, we just add the COEFFICIENTS (the numbers that are next to and multiplied with the letters) together. So, for 2x + 3x, we do 2+3 = 5. So 2x + 3x = 5x. Remember to keep the x!

Best ResponseYou've already chosen the best response.0So basically 6(x+y). Is the same as (6x)+(6y) Do you get it now?

Best ResponseYou've already chosen the best response.0Simplifying 6(x + y) + (x + 1y) (x * 6 + y * 6) + (x + 1y) (6x + 6y) + (x + 1y) Remove parenthesis around (x + 1y) 6x + 6y + x + 1y Reorder the terms: 6x + x + 6y + 1y Combine like terms: 6x + x = 7x 7x + 6y + 1y Combine like terms: 6y + 1y = 5y 7x + 5y So like this? @UsukiDoll sorry Im new

Best ResponseYou've already chosen the best response.1It's sort of like saying, let x mean balls. I have 2 balls, and another 3 balls. That means I have 2 balls + 3 balls, which is 5 balls.

Best ResponseYou've already chosen the best response.0there is no other number for me to do that with..... (ex: the whole (xy) thing is confusing because i dont no what to do about it)

Best ResponseYou've already chosen the best response.1@Frascamr it's ok... but please refer to this website for more information about the code of conduct. http://openstudy.com/codeofconduct As for the explanation. I think it's ok, but a bit too much. try step by step :)

Best ResponseYou've already chosen the best response.0when you don't see the number it is understood the number is 1

Best ResponseYou've already chosen the best response.1Imagine that there's a 1 outside (xy), because really, 1 is multiplied by everything all the time. The number 6? Yeah, that's just 6 times 1. So (xy) can be thought of as 1(xy), which, if you expand the brackets, just gives you x  y

Best ResponseYou've already chosen the best response.0i got 5x + 4Y which i no is wrong because it isnt a option

Best ResponseYou've already chosen the best response.1Ok, let's go through stepbystep. So we start with... 6(x + y) + (x  y). Now what? Let's expand the brackets. Do you know how to do that?

Best ResponseYou've already chosen the best response.0yea you put it as 6x  6y + 1x  1y ....... i think

Best ResponseYou've already chosen the best response.1everything is right so far except the sign for 6(x+y)

Best ResponseYou've already chosen the best response.1Almost! But it's 6x + 6y, not 6x  6y, where did the negative sign come from?

Best ResponseYou've already chosen the best response.16x + 6y + x  y . now combine like terms

Best ResponseYou've already chosen the best response.0oh now i see the answer well at least half 7x unless 7x is the answer

Best ResponseYou've already chosen the best response.1you can rearrange the equation to make the computation easier 6x + x + 6y  y .

Best ResponseYou've already chosen the best response.1nooooooooooo... we just combine like terms. we can't combine x and y together

Best ResponseYou've already chosen the best response.16x + x + 6y  y I'm going to factor out the variables to make it easier x(6+1)+y(61)

Best ResponseYou've already chosen the best response.1almost... x is correct y isn't what's 61

Best ResponseYou've already chosen the best response.1yes so we have 5y so our answer is 7x+5y
