3x^3+6x^2+8x+24 +47/(x-2)
R>-6
Please correct me if I’m wrong
{2x + 3y = 18
x + 7y = 31}
2x+ 3y = 18
x=31-7
2(31-7)+3y=18
y=4
x=31-7*4
x=3
(x,y) = (3,4)
2 is the answer because 2=2 but 2 doesn’t =0.
Note that 2x-y=8 can be solved for y: y=2x-8. This is identical to the first equation. The graph of one is exactly the same as the graph of the other. Thus, the two equations are dependent.
