In the following exercises, evaluate the following expressions.
$6 x + 3 y - 9 when x = 6, y = 9$

Short Answer

Expert verified

The required value is 54.

Step by step solution

Step 1. Given information.

The given expression is:

$6 x + 3 y - 9$

We have to evaluate the given expression for $x = 6 and y = 9$ .

To evaluate an expression means to find the value of the expression when the variable is replaced by a given number.

Step 2. Replace x with 6 and y with 9 in the given expression.

$6 x + 3 y - 9 = 6 (6) + 3 (9) - 9$

Follow the order of operations,

$= 36 + 27 - 9 = 63 - 9 = 54$

The value of $6 x + 3 y - 9 when x = 6, y = 9$ is 54.
