Question

Express this statement as an equation:
My age is 3 years less than twice the age of my brother. Assume that my brother’s age is x and my age is y.

• A. x - 2y = 3
• B. 2x + y = 3
• C. 2x - y = 3
• D. 3x - 2y = 0

Answer 1

The correct option is C 2x - y = 3

Let my brother’s age be x and my age be y. Then, twice the age of my brother is 2x.
My age is equal to 3 less than twice my brother's age.
So, this can be represented as $y=2x-3$.
$\therefore 2x-y=3$ is the required equation.
