@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?

i 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

or if not, get them both in terms of 6x

2x + 5y = 13 so 6x + 15y = 39 and 3x  4y = 8 so 6x  8y = 16 therefore 6x = 39  15y and 6x = 16 + 8y

2x + 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

6x = 39  15y = 16 + 8y 39  15y = 16 + 8y 39 = 16 + 23y 23 = 23y 1 = y

The next one I have I have to get the value of y.. is it the same way we get the value of x?

Jack1Best ResponseYou've already chosen the best response.0
exactly 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

You 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

so 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
 8 months ago

Jack1Best ResponseYou've already chosen the best response.0
sorry, 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
 8 months ago

Jack1Best ResponseYou've already chosen the best response.0
so 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?
