Best ResponseYou've already chosen the best response.0@Jack1 for ones like these: there is no parenthesis, or exponents, so I staret with the multiplication.. I want to get my y's to one side.. how do I do that? I divide them?

Best ResponseYou've already chosen the best response.0i like to subtract first to isolate the one term on one side so 2x + 5y = −13 2x = 13 5y x = (13/2)  (5/2)y

Best ResponseYou've already chosen the best response.02x + 5y = 13 so 6x + 15y = 39 and 3x  4y = 8 so 6x  8y = 16 therefore 6x = 39  15y and 6x = 16 + 8y

Best ResponseYou've already chosen the best response.02x + 5y = −13(1) 3x − 4y = −8 (2) in equation 1 2x=135y x=135y/2 put x in equation 2 3(135y/2)4y=8 3915y/24y=8 3915y8y=16 23y=16+39 23y=23 y=1 put y in equation 1 2x + 5y = −13 2x+5(1)=13 2x5=13 2x=13+5 2x=8 x=4

Best ResponseYou've already chosen the best response.06x = 39  15y = 16 + 8y 39  15y = 16 + 8y 39 = 16 + 23y 23 = 23y 1 = y

Best ResponseYou've already chosen the best response.0The next one I have I have to get the value of y.. is it the same way we get the value of x?

Best ResponseYou've already chosen the best response.0exactly the same way, it doesn't matter if the term is called x or y or q, its all the same when using simultaneous equations

Best ResponseYou've already chosen the best response.0You are not even teaching her the right thing.Also,You are very mean and you don't know how to respond to someone..when they ask you a question. I might link you this: http://openstudy.com/codeofconduct Next time if you're mean to me.I'll report you to Preetha. @Jack1

Best ResponseYou've already chosen the best response.0so thats equation 1 in a form we can use now for equation 2: 2x − 6y = −14 change it so u get 10x on one side

Best ResponseYou've already chosen the best response.0sorry, back to equation 1: it should be 10x = 22 + 6y, not 10x = 22 + 6, my bad now equation 2: 2x − 6y = −14 (times 5) 10x  30y = 70 (add 30y to both sides) 10x  30y + 30y = 70 + 30y 10x = 70 + 30y

Jack1

Best ResponseYou've already chosen the best response.0so equation 1 is now 10x = 22 + 6y and equation 2 is now 10x = 70 + 30y so 10x = 22 + 6y = 70 + 30y 22 + 6y = 70 + 30y can u solve from here?
