The students asked their math teacher to tell them her age. She didn’t want to tell them, but she replied, “If you take two years from my present age the result will be three times my son’s age, and seven years ago my age was twice what his will be in two years.” How old is the teacher?

teacher's age --- x
son's age ---- y

x-2 = 3y
x = 3y+2

x-7 = 2(y+2)
3y + 2 - 7 = 2y + 4
y = 9
x= 3(9)+2 = 29
