From the information given, it was stated that Kim has 8 dollars less than twice Ricky. This will be:
= (2 × x) - 8.
= 2x - 8
Also, Ricky has x dollars. Therefore, the amount that they have together will be:
= 2x - 8 + x
= 3x - 8

For the answer to the two questions above,
3x + 2y = 36.50 (I)
2x + 5y = 50 (II)
Eliminating x from the two equations by subtraction:
first we multiply equation I by 2 and equation II by 3
6x + 4y = 73
6x + 15y = 150
Subtracting the two,
-11y = -77
y = 7
He earns $7 at the coffee cart
Substituting y into equation I,
3x + 14 = 36.5
x = $7.50
So we can conclude that, he earns a greater wage of $7.50 at the library,
