Best ResponseYou've already chosen the best response.1Haven't done this type of question for long, still give it a try :P 4x3y+20=0 => 4x 3y = 20 3x+2y2=0 => 3x +2y = 2 Determinant: 4 3  Δ = 3 2  = (4x2)  (3x3) = 17  20 3  Δx =  2 2  = 34 x = (Δx) /Δ = 34 / 17 = 2  4 20  Δy = 3 2  = 68 y= (Δy ) / Δ = 68/17 = 4 Got it?

Best ResponseYou've already chosen the best response.1@Eric_Playsinacoolway , i don't think you are interpreting it correctly...giving solutions is ok as long as it provided stepbystep help with explanations giving multiple answers with no guidance is what is frowned upon
