Solve by elimination 5x+4y = 12 3x - 3y = 18 solve and provide steps.

5x + 4y = 12   ⇒   3(5x + 4y = 12)   ⇒   15x + 12y = 36

3x - 3y = 18   ⇒    4(3x - 3y = 18)   ⇒   12x - 12y =  72  

                                                              27x         = 108

                                                                =  

                                                                   x        =   4

5x + 4y = 12   ⇒   5(4) + 4y = 12   ⇒  20 + 4y = 12   ⇒   4y = -8   ⇒   y = -2

x = 4, y = -2

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
