Question 336074
w = age of weiss
s = age of soron


w = s + 18
w = 2.5 * s


since they are both equal to w, then they are both equal to each other, so you get:


s + 18 = 2.5*s


subtract s from both sides of the equation to get:


18 = 2.5*s - s = 1.5*s


divide both sides of the equation by 1.5 to get


18/1.5 = s


solve for s to get:


s = 12


soron is 12 years old


weiss is 12 + 18 = 30 years old.


weiss is also 2.5 * 12 = 30 years old.


your answer is that soron is 12 years old and weiss is 30 years old.
