Answer:
Eric earnings equals $7
Step-by-step explanation:
Let amount earned by Robert = $10
Amount earned by Eric = $x
Robert earnings = 2x - 4
2x - 4 = 10
2x = 10 + 4
2x = 14
Divide both sides by 2
x = 14 / 2
= 7
x = 7
Eric earns $x which is equal to $7
Eric earnings equals $7

Good luck !
285-5x=340-10x
285-5x-(340-10x)=0
-5x-(-10x+340)+285=0
-5x+10x-340+285=0
5x-55=0
5x=55
x=55/5
x=11
