John was asked how old he is. He said in 2 years I will be twice as old as I was 5 years ago. I guessed 12, am I right? x = John's age now x + 2 = 2(x - 5) {in 2 years, he will be two times what he was 5 years ago} x + 2 = 2x - 10 {used distributive property} 2 = x - 10 {subtracted x from each side} x = 12 {added 10 to each side} John is 12 - Algebra House
