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

Answer 1

Say x is the number of hours Isac worked. Therefore, (x+6) is the number of hours Ruby worked and 4(x+6) is the number of hours Svetlana worked.

x+(x+6)+4(x+6)=126
Now solve for x and then plug the number back into each equation.

Answer 2
