Question

Problem is attached in the picture.

Answer 1

its a "system" so it means that if there is only one solution to it they both have the same values for x and y.... in other words, they both intersect at that point (x,y) on the graph

Answer 2

do i plug the number in the parentheses into the equations?

Answer 3

To solve it you need the x terms and the y terms on the same side... NO, no pluging in here because those are just numbers to show you what equations they are, eq1 and eq2

Answer 4

so bring the -9y over to the other side in eq(2) as a +9y with the x

Answer 5

then the equations will look like...

Answer 6

x + 9y = 3.........and........
x + 9y = 6

Answer 7

but as you can see, not so clearly, nothing works for x and y here... there is no solution.

Answer 8

you can multiply eq2 now by (-1) on both sides and see it like this...

Answer 9

ooooo so its no solution?

Answer 10

x + 9y = 3
-x -9y = -6
-------------
0 + 0 = -3 <--------- zero does not = 3 so... NO SOLUTION

Answer 11

Yay , thanks. You've been alot of help lol.
