why is

x+y=21000
y=3x
substitute y=3x into eqn 1
x+3x=21000
4x=21000
x=5250

sub x=5250 into eqn 2
y=3*5250
=15750
(why is this not right?)

why did chatgpt do 400x+450y or smth like that

#

Where X is the amount of blocks with 400 seats
Where Y is the amount of blocks with 450 seats
The correct equation is:
400X + 450Y = 21000

#

You count blocks with x,y, not actual seats

From the previous equation, and the ratio you get
400X+450Y = 21000
-3X + Y = 0

After solving for both of them, X+Y is your answer.
