Question

solve the system of equations:
5x+-y=-3
x+-4y=9

Answer 1

@reginad99 1) y=5x+3x
2) Y=1/4-9/4
This solves for y.

Answer 2

multiply equation 1 with -4 on both sides so we get
-20x+4y=12 and add to equation 2
x-4y=9 we get -19x=21 or x=-21/19 and y=-48/19

Answer 3

idk i tried!

Answer 4

I would do these equations using the elimination method

Answer 5

@kelliegirl33 i have no idea what method i used, i just did it.

Answer 6

or substitution....x = 9 - 4y, and just sub 9 - 4y in for x in the 1st equation, and then solve for x
