Question

me ayudan es de plantear ecucaciones (perimetros iguales) me las mandan con el prosedimiento​

Answer 1

$2(x - 5) = 3x - 17 \\ 2x - 10 = 3x - 17 \\ - 10 + 17 = 3x - 2x \\ 7 = x$

$3(2 - x) = 18 - 1 \\ 6 - 3x = 17 \\ 6 - 17 = 3x \\ - 11 = 3x \\ - \frac{11}{3} = x$

$x - 13 = 3(1 + 19) \\ x - 13 = 3 \times 20 \\ x - 13 = 60 \\ x = 60 + 13 \\ x = 73$

$60x - 1 = 3(1 + 12x) \\ 60x - 1 = 3 + 36x \\ 60x - 36x = 3 + 1 \\ 24x = 4 \\ x = \frac{4}{24} \\ x = \frac{1}{6}$

$3(x + 4) = 4x + 1 \\ 3x + 12 = 4x + 1 \\ 12 - 1 = 4x - 3x \\ 11 = x$

$2(3x - 49) = x + 14 \\ 6x - 98 = x + 14 \\ 6x - x = 14 + 98 \\ 5x = 112 \\ x = \frac{112}{5}$
