Gregory is x years old. Daisy is 2 years older than Gregory. The sum of their ages is 40.
(a) Form an equation in terms of x.
(b) Solve the equation and work out Gregory's and Daisy's ages.

Answer 1

gregory is 19 years old  and daisy is 21 because 21 is two more that 19 but 19 +21=40

Answer 2

The correct answer is:

Gregory is 19 years old  and daisy is 21

Applying linear equation

Let,

Age of Gregory = x years

Age of Daisy = (x+2) years

An equation in term of x

x + (x+2) = 40

2x + 2 = 40

2x = 40 - 2

x = $\frac{38}{2}$

x = 19

∵ 19+21=40

⇒ Gregory is 19 years old

⇒ daisy is 21 years old
