Why do you have to multiply the first equation by two and the one next to it by -1?

“A, B, and C have 2150 yen collectively. A has 120 yen more than B does. After C gives B 2/5ths of his money, B now has 220 yen more than A. How much money did A originally have?”
They say it's a problem that even middle schoolers can solve, but wow. Maybe I'm just dumb. I can't figure anything out.

(B+120) + B + C = 2150
An + (B+2/5C) + 3/5C = 2150

?

Honestly, I have never seen equation systems solved in this way. At my school we always isolate the first variable, so it can be but into the next equation, to solve the next variable so it can be put into the last: so you'll end up with an equation with only 1 variable. Therefore this is mindblowing to me. Thank you!
