Whats the Answer To x+y =-9 and 5x-2y=32
Use Elimination: x + y = -9(-/+)5x - 2y = 32~~~~~~~~~~~~~(multiply top by 2) 2x + 2y = -18(+) 5x - 2y = 32~~~~~~~~~~~~~~ 7x + 0y = 14 7x = 14 x = 2Put "x" into one of the equations: x + y = -9 (2) + y = -9 y = -11Your solution is (2, -11) Right? :-D
I don't know
Can't help you on this one lol sorry
use bing calculator or Google it.
The first one is x= -4 and y = +5 and I'm not sure about the second one. Sorry :( and good luck on the homework!
Umm I got for the second one x=2/5y+32/5 because u can't simplify any more n for y, I got y=5/2x+16
Ginger609 is right.
