"John is 5 times as old as he was 40 years ago so how old is he now"

x = his age now
x - 40 = his age 40 years ago

x = 5(x - 40){now, he is five times his age 40 years ago}
x = 5x - 200 {used distributive property}
-4x = -200 {subtracted 5x from both sides}
x = 50 {divided both sides by -4}

John is 50 now
