Question

solve the system 2x+3y=6, x-3y=5 by graphing. And is there a solution?

Answer 1

try substituting

Answer 2

do you have a graphing calculator?

Answer 3

x=3.666666 y=-.444444

Answer 4

2x+3y=6, x-3y=5
x=3y+5
plug x into 2x+3y=6 to find out the y coordinate of the intersection

Answer 5

x=(11/3) y=(-4/9)

Answer 6

then plug in the y value after solving out into either equation to find the x value of the intersection

Answer 7

is it x=0 and y=2

Answer 8

no it is x=11/3 and y=-4/9

Answer 9
