Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 36. How old is each sister?
2 answers:
A)
Let x = sister's age
<span>Kim's age is twice that of her sister
</span>so Kim's age = 2x
<span>Kim’s age + Sister’s age = 36
equation:
x + 2x = 36
b) solve the equation </span>x + 2x = 36
x + 2x = 36
3x = 36
x = 36 / 3
x = 12
Kim's age = 2x = 2(12) = 24
answer
Sister's age is 12 and Kim's age is 24.
A. 2x+x=36
x=12
B. 2(12)+12=36
24+12=36
