Answer 1

The value of the sum expression $\frac{x}{x +3} + \frac{3}{x + 3}$ is 1

How to determine the sum?

The expression is given as:

$\frac{x}{x +3} + \frac{3}{x + 3}$

Take the LCM of terms of the expression

$\frac{x}{x +3} + \frac{3}{x + 3} = \frac{x + 3}{x +3}$

Evaluate the quotient of x + 3 and x + 3

$\frac{x}{x +3} + \frac{3}{x + 3} = 1$

Hence, the value of the sum expression $\frac{x}{x +3} + \frac{3}{x + 3}$ is 1
