Question

One her next birthday, Zara’s age will be 10 years. If y represents her age on her next birthday. Write an equation to find y and find her present age

Answer 1

Y is next year, so subtract 1 year from Y to get present age, X.

Y - 1 = X

We know Y is her age next year which is 10 years. So, Y=10

10-1=X
X =9 years.

She is 9 years older and will be 10 years next birthday.
