Question

Please help.......How do I make a table of solutions for the equation 3x+2y=-18 using -2 and three other numbers for my x axis and using 3 and three other numbers for my y axis.Ok I was only given two numbers for x which was 2 and 0 so now I need two more numbers for x. The same with y. I was only given two numbers which was 3 and 0, so I need two numbers to complete the the table. Hope u understand

Answer 1

Well, here's how I'd start: just plug in some arbitrary values for x and find the corresponding value of y, then put that into your table.

So, for example, let's start with your given number x=-2. If we evaluate the expression with that assumption then we have:
3*(-2)+2y=-18
we can simplify that to read...
-6+2y=-18
simplify further...
2y = -18 - (-6)
2Y = -12
Y =-6

So, the first line in your table would be
X | Y
-2 |6

Answer 2

So how would I find the x if the y is 3?
