Question 106437: Find four solutions for the equation 3x + 5y = 15. I don't know if I did my solutions right and if they make sense.

3(3) + 5y = 15
9 + 5y = 15 Solution is (3,1)
5y = 6
y = 1

3x + 5(0)= 15
3x + 0 = 15 Solution is (5,0)
3x = 15
x = 5

3(0) + 5y = 15
5y = 15 Solution is (3,0)
y = 3

3x + 5(6) = 15
3x + 30 = 15 Solution is (6,-3)
3x = -15
x = -5

You can put this solution on YOUR website!
A couple of mistakes, let's go through.
3%283%29+%2B+5y+=+15
+9+%2B+5y+=+15+
+++++5y+=+6
+++y+=+highlight%281%29
That answer is wrong. It should be,
+++y+=+6%2F5
(3,1.2)
3x+%2B+5%280%29=+15
3x+%2B+0+=+15++++
++3x+=+15
x+=+5
Good answer, (5,0).
3%280%29+%2B+5y+=+15
++++5y+=+15
++y+=+3
Good answer, but you re-arranged your (x,y) ordered pair.
It should be (0,3).
3x+%2B+5%286%29+=+15
+3x+%2B+30+=+15+
+++3x+=+-15
+x+=+-5
Good answer, but you mistakenly wrote your (x,y) ordered pair.
It should be (-5,6).

The equation is for a line.
All the solutions must fall on the line.
Good luck.
