Question

Zia is 8 years younger than twice his sister Sahsa's age. Zia is 32 years old. Let s represent Sasha’s age. During the Strategize step of the five-step problem-solving plan, which expression would you use to represent Zia’s age?2s + 88s−2s−82s−8

Answer 1

If Zia is 8 years younger than twice her sisters Sasha's age. This must be the expression. 
2S = Z-8

Where:
Z is Zia's age 
S is Sasha's age

Now we rearrange for Z:
Z = 2S + 8


Hope this helps!
