Answer:
Rene = 18
Sister = 12
Step-by-step explanation:
Let
Rene's age be 6+x
Her sister's age be x
Given that:
6+x+10+x+10 = 50
To calculate their ages, we have to find out the value of x. To find the value of x, rearrange and solve the above equation:
6+x+10+x+10 = 50
26 + 2x = 50
2x = 50-26 = 24
x = 12
We said at the start that Rene's age was 6+x, so her age = 12+6 = 18
Rene's sister's age = x = 12
Hope this helps
