I NEED HELP!

56 years ago, he was 122

188+56=244
x + 244 = 3x
x=122

He is now 122+56, that is... 178
He'll be 366 in 188 years time: thrice 122.

Thanks soooo much!

Here's a hint solve for this equation:

188 + a = 3(a-56)

then you'll get your answer

if you aren't good at math here is another hint

divide both sides by 3 to start
