An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Age of John = m
Age of Keisha = n
m = 6 + n
m + n = 4n
m = 9
n = 3
The age of John is 9
The age of Keisha is 3
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Let the age of John = m
Let the age of Keisha = n
Now,
John is 6 yearsolder than Keisha.
This means,
m = 6 + n _____(1)
Together their ages equal fourtimesKeisha's age.
This means,
m + n = 4n _____(2)
From (1) and (2) we get,
6 + n + n = 4n
6 + 2n = 4n
6 = 4n - 2n
6 = 2n
n = 3
Now,
m = 6 + n
m = 6 + 3
m = 9
Thus,
The age of John is 9
The age of Keisha is 3
