Rozwiaz algebraicznie i graficznie uklad Rownani 1. {y = -2x + 2 {4y + 3x = -12 2. {y - 3x +4 = 0 {4 = x

1{y=-2x+2 {4(-2x+2)+3=-12 y=-2x+2 -8x+8+3=-12 y=-2x+2 -8x=-12-8-3 y=-2x+2 -8x=-23 y=-2x+2 x~~2,88 y=-5,76+2 x~~2,88 y=-3,76 x~~2,88 zaraz podam drugi przyklad :) 22. {y - 3x +4 = 0 {4 = x {y-12=-4 {x=4 {y=8 {x=4 :)
