-5x-3y=9
4x-187-54=0
4x=241
x=60.25
To get y
Substitute for x in equal one
-5(60.25)-3y=9
-301.25-3y=9
-3y=9+301.25
-3y=310.25
y=-103.4

Answer:
Brother's money = $6
Money I have = $18
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given:
<em>I have 3 times as much money as my brother:
</em>
Money I have = 3x
Where x is the money that my brother has:
Brother's money = x
<em>Our total is $24
</em>
So, 3x+x =24
Solving for x
3x+x=24
4x =24
x =24/4
x = 6
Replacing with the value of x.
Brother’s money = x = $6
Money i have = 3x =3(6) = $18
