Question 166261: X is Xavier’s age, Y is Yvette’s age, and Z is Zevon’s age. Yvette is twice as old as Xavier. If Zevon’s age is increased by 10 he will be as old as Yvette. Write an equation that shows Zevon’s age (Z) only in terms of Xavier’s age (X).
I am having difficulty figuring this out so far I came up with Z = 2X + 10. Can someone please help. Thank you

X is Xavier’s age, Y is Yvette’s age, and Z is Zevon’s age. Yvette is twice as old as Xavier. If Zevon’s age is increased by 10 he will be as old as Yvette. Write an equation that shows Zevon’s age (Z) only in terms of Xavier’s age (X).
----------------
Y = 2X
Z+10 = Y
---------
Z = Y-10
Substitute to get:
Z = 2x - 10
