Answer 1

Answer:

$3 - a$

Step-by-step explanation:

Given that when you add two numbers together the result is 3.

The greater of the number is given as a.

Let "x" represent that lesser number.

Thus:

$a + x = 3$

To make x the subject of the formula. Subtract a from both x.

$a + x - a = 3 - a$

$x = 3 - a$

Therefore, the expression that represents the lesser number, x, is:

$3 - a$
