Thanks
OpenStudy (jhannybean):
4x + 5y = 7 3x – 2y = –12 Let's eliminate out x's first. Common multiple is 12, so multiply the first equation by -3 and the second equation by 4 -3(4x +5y = 7) 4(3x-2y = 12) What do you get?
OpenStudy (anonymous):
-2,3
OpenStudy (anonymous):
you can eliminate y instead of x too right?
