Question

I have 3 time as much money as does my brother. our total is $24. how much do we have

Answer 1

Your brother has 3x you have x
So x+3x=24
4x=24
x=6
You have 6$ and your brother has 18$

Answer 2

I have $18 and my brother has $6.

Explanation:

x - brother's money

3x - my money

$24 - our money

The equation:

x + 3x = $24

4x = $24

4x : 4 = $24 : 4

x = $6

3x = 3 · $6 → 3x = $18
