Lea is two years older than Mia.The sum of their ages is 20.Find their present ages.
So if the SUM of their age is 20, what does SUM mean?
@aera heres a hint. Your going to undo the problem.
Lia was 11 and Mia was 9. 9 plus eleven equals twenty, and 11 is two numbers larger than nine. :)
SUM means to add.
L = M + 2
L + M = 20
Substitute M+2 for L in the second equation and solve for M. Insert that value into the first equation to solve for L. Check by putting both values into the second equation.
To determine Lea and Mia's present ages, let's break down the information given:
Let's assume Mia's age is "x."
Since Lea is two years older than Mia, Lea's age would be "x + 2."
According to the problem, the sum of their ages is 20, so we can write the equation:
x + (x + 2) = 20
To find their present ages, we need to solve this equation.
