Question 1176753
s = suzy's age
b = her brother's age
m = her mother's age.


equations are:


s = 1.5 * b
s = m - 25


since s = 12, the equations become:


12 = 1.5 * b
12 = m - 25


solve for b in the first equation to get:


b = 12 / 1.5 = 8


solve for m in the second equation get:


m = 12 + 25 = 37


her brother is 8.
her mother is 37.


those are your answers.
