Question

usando teorema de tales,calcule o valor de x e y
me ajudem por favor

Answer 1

y+1 / 2y -1 = 5/3 = x-6 / 4

$y+1 / 2y -1 = 5/3 = x-6 / 4 \\\\ Para.Y\\\\ y +1 /2y -1 = 5/3 \\ 3(y+1) = 5(2y-1)\\ 3y +3 = 10y -5\\ 3+5 = 10y -3y\\ 8 = 7y\\ y=8/7\\ \\ Para.X\\ 5/3 = x-6 / 4\\ 5.4 = 3(x-6)\\ 20=3x-18\\ 20+18=3x\\ 38=3x\\ x = 38/3$
