Ok so ummmm idk how to speck in that but well ummmmm idk
1) let both have x ,
so putting in eqn ;
4x+0.50 = 9x-3
5x=2.50
x=0.50
therefore both have 50 p in the beginning !!
2) let the number be x
so in eqn;
(x+18)/2=5x
x+18=10x
9x=18
x=2
so the number must be 2 !!
if you have still any problem, comment !!

Step-by-step explanation:
<u>Step 1: Define equation</u>
4x - 5 = x - 1 + 3x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 4x - 5 = 4x - 1
- Subtract 4x on both sides: -5 ≠ -1
Here we see that -5 does not equal -1.
∴ This equation has no solutions.
