I can't solve this math question:

A and B earn together 5500 bux

B earns 20% more bux than A

How much bux does A earn?

I really can't think of any way to solve this.

Divide 5500 by 2, subtract 20% from one side, add the difference to the other. The greater amount will be B bux; the lower amount A bux.

WARNING: Do not divide 5500 by 0

That was pretty easy. I'm pretty proud I actually solved it.

Still dum here.

>>Divide 5500 by 2,

2750

>>subtract 20% from one side, add the difference to the other

20% = 550

2750 - 550 = 2200

2750 + 550 = 3300

So how do you get the 2500?

Let a = amount A earns, b = amount B earns. So you know that:

a + b = 5500
b = 1.2a

Easy. Now you just solve that system of equations there.

This is for >>1:
(1) a + b = 5500
(2) b = 1.2a
sub (2) into (1)
a + (1.2a) = 5500
2.2a = 5500
a=5500/2.2=2500

There should be an "any questions"-board like on 2ch.
