Question

Evaluate the expression if x=12, y=8, and z=3 4x-yz

Answer 1

`\huge \boxed{24}`

Explanation:

Let if x=12, y=8, and z=3.

`4(12)-(8)(3)`

Evaluate.

`48-24`

`=24`

Answer 2

Start by substituting the appropriate numbers in for

your variables, using parenthses as you go.

You'll get 4(12) - (8)(3).

Now think about your order of operations.

Multiplication comes before subtraction.

So first multiply 4(12) to get 48.

So we have 48 - (8)(3).

Now multiply (8)(3) to get 24.

So we have 48 - 24 which is 24.
