Question

In 8 years, a girl will be 3 years older than twice her present age. How old is she now
​

Answer 1

5

Explanation:

You can express this as a system of equations:

x in this instance will be her present age.

x + 8 = 2x + 3

simply solve for x after this by subtracting three and x from both sides, and you’ll find that x is 5.
