A-52.

Write an equation that represents this situation using only one variable.

Mairé is thinking of two numbers. The first number is $14$ less than the second number. When she adds them, she gets $40$. Help Mairé figure out the numbers.

Let the second number be $x$. Write an expression for the first number in terms of $x$.

The equation you need to solve is $x + (x − 14) = 40$.
