Let Lin be x years old.
Lin = x
Frank = 4x
<span>The difference in their ages is equal to Lin’s age plus 8
</span>⇒4x - x= x + 8
Solve x:
4x - x= x + 8
Combine like terms:
3x = x + 8
Take away x from both sides:
2x = 8
Divide by 2 on both sides:
x = 4
Lin is 4 years old.
Frank is 4 x 4 = 16 years old.
