Question

Sendo t//v, determine o valor de x//y

Answer 1

$\frac{a}{2} + 10 = \frac{a}{3} + 30$
$\frac{a + 20}{2} = \frac{a + 90}{3}$
$3.(a + 20) = 2.(a + 90) \\ 3a + 60 = 2a + 180 \\ 3a - 2a = 180 - 60 \\ a = 120$
$y = \frac{a}{3} + 30 \\ y = \frac{120}{3} + 30 \\ y = 40 + 30 \\ y = 70$
$x = \frac{a}{2} + 10 \\ x = \frac{120}{2} + 10 \\ x = 60 + 10 \\ x = 70$
