Question 428458
"Here is the word problem: If three times Kathy's age is decreased by 36, the result is twice Kathy's age. How old is Kathy?"


x = Kathy's age


3x - 36 = 2x {three times her age minus 36 equals twice her age}
-36 = -x {subtracted 3x from both sides}
x = 36 {divided both sides by -1}


Kathy is 36
