One month, ruby worked 6 hours more than Isaac, and Svetlana worked 4 times as many hours as ruby. Together they worked 126 hours find the number of hours each person worked.

Let x hours be the number of hours Issac worked

x+6 hours be the number of hours Ruby worked

4 (x+6) hours be the number of hours Svetlana worked.

x + x + 6 + 4 (x+6) = 126

x + x + 6 + 4x + 24 = 126

6x + 30 = 126

6x = 96

x = 16

Therefore, Issac worked 16 hours.

Ruby worked 16+6 = 22 hours

Svetlana worked 22 * 4 = 88 hours.
