So elimination method is basically adding the equations and canceling out variables. -6x + 6y = 6 -6x + 3y = -12 The eaiest way to solve is by multiplying the bottom equation by -1. -6x + 6y = 6 6x - 3y = 12 Now you add the eqautions. 3y = 18 Divde 3 from both sides. y = 6 Now plug in 6 into any of the original two equations. Lets use the first one. -6x + 6(6) = 6 -6x + 36 = 6 Subtract 36 from both sides. -6x = -30 Divide -6 from both sides. x = 5 So your solution is (5, 6). I hope this helps love! :)
a) Yes, the more time the plant spend in sunlight, the taller it grows. for example, the plant that spend no time in the sun only grows to 4cm while the plant that spent 9 hours in the sun grew to 31
Well for example: 10/1 divided by 1/2 What you will do you would flip 1/2 it would now become 2/1 Then you change the sign to multiplication so your equation will look like 10/1*2/1 then just multiply from there on out.
