Thanks in advance guys!!! :)
5x - 2y = -16 3x + 5y = -22 OK for this two ways, well actually 3. First, put in x and y into both equations and see if it works. Do you know elimination?
Or substitution?

Well... eliminate either x or y by making the values of them in both equations the same. So for this one, I will eliminate x. The LCM of 5 and 3 is 15. In both equations we want 15x. Multiply the first equation by 3, and the second by 5 to get: 15x - 6y = -48 15x + 25y = -110 Now Subtract one from the other: 15x - 6y - (15x + 25y) = -48 -(-110) -31y = 62 y = -2 Now substitute y = -2 into any of the first equations. I'll choose eq 1 3x + 5(-2) = -22 3x - 10 = -22 3x = -12 x = -4 And there you have it
Thank you so much!!! :)
Your AMAZING! :)
Your welcome. Do you know the other method? Substitution?
Or you could use matrices...
You could indeed
thank you! :)
so much for your help! :)
matrices? what dat? @Dido525
Never mind then :P . Wait till linear algebra.
