Sagot :
Answer:
let's assume that the age of her sister now is 28 which if divided by 2 (because joanne's age is twice or 2×) the quotient will be 14 then her age 6 years ago will be 8.
Step-by-step explanation:
x/2-6=y
x=age of joanne now
y=age of joanne 6 years ago
Answer:
x - 6 (in terms of Joan's age) or 2y - 6 (in terms of her sister's age)
Step-by-step explanation:
Let x be Joan's present age and y be her sister's present age.
x = 2y
Joan's age 6 years ago = x - 6.
∴ x - 6 = 2y - 6.
