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?
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
