One month, Ruby worked 8 hours more than Isaac, and Svetlana worked 4 times as many hours as Ruby. Together they worked 148 hours. Find the number of hours each person worked.

Isaac hrs = x

ruby hours = x+8

Svetana = 4(x+8)               All of this is given in the Q

 

added together all of these hours = 148

 

x   + x+ 8    +   4 (x+8)  = 148

6x +40 = 148

6x = 108

x = 18 = Isaac hours

Ruby = x+ 8 = 26

Svetlana = 4(x+8) = 104 hours
