To solve this equation by elimination, what you would do is multiply one of the equations by -1, or distribute -1 to each term in the equation, any of the 2 equations. Then align the equations and add them together.

-(X + 3y = 3)
-X - 3y = -3

-X - 3y = -3
X + 6y = 3
__________
3y = 0
y = 0/3 = 0.

Now we can solve for x, by simply plugging the value of y into any of the 2 equations.

X + 6y = 3
X + 6(0) = 3
X + 0 = 3
X = 3.

The solution to your system of equations would be (3,0).

Check this by plugging in the point to the other equation and see if it is true.

X + 3y = 3
(3) + 3(0) = 3
3 + 0 = 3
3 = 3.

Thus it is the solution.

lakkis [162]
9 packets.

36 divided by 3 = 12
49 divided by 5 = 9.8
76 divided by 7 = 10.8

Maximum packets that can be obtained is 9 packets because only 9 packets with 5 green beads each can be packaged.

No -- other factors will influence whether your happy or not. Saying that is true is inductive reasoning, which is prone to error
