Question 668002
3x+y=6
{{{highlight(y = -3x + 6)}}}
...
2x-3y=15
2x - 15 = 3y
{{{(cross(3)y)/cross(3) = 2x/3 - 15/3}}}
{{{highlight_green(y = (2/3)x - 5)}}}
...
{{{graph(300,200,-1,5,-5,1,-3x+6,(2/3)x-5)}}}
...
Confirm
{{{-3x+6 = (2/3)x-5}}}
-9x + 18 = 2x - 15
15 + 18 = 2x + 9x
33 = 11x
x = 3
...
y = -3(3)+6 = -3
...
Solution:(3, -3)
