  • nessa eliminação não entendi essa reta -3x1-3x2=-54 de onde ela sai

    obrigado

  • e porque você substitui o x1 e x2 por zero para achar os pontos.

    2*0+5x2=60 -> x2=60/5 -> x2= 12

    2x1+5*0=60 -> x1=60/2 -> x1=30

    ai você traça a reta no ponto 12 em x2 e no ponto 30 em x1

  • 3:00 por quê 2x1 + 5x2 = a 60 e foi marcado 30 em x1?
