Maria is x old her sister is twice her age write an expression in simplest form that represents the sum of the ages of the two sisters

x*2=y+x= both

Step-by-step explanation:

y would be her sister age, you would have to multiply Marias age by 2 to get her sisters age since her sister is twice her age then you have to add them together to get the sum of both their ages.

Example: maria is 16

               16*2=32+16=48
