You have one unknown y and 2 numbers 12 and 8

We do not know his age now, then

Let his age now is y

From 8 years ago he was 12 years old

That means If we subtract 8 from his age now the answer should be 12

Then subtract 8 from his age now y to get 12

The equation is y - 8 = 12

To solve the equation add 8 to both sides, to move 8 from the left side to the right side

y - 8 + 8 = 12 + 8

y = 20

His age now is 20
