Question

Y = 3; Evaluate this expression: 4y - 12 = ?

Answer 1

Given:

`y\text{ = 3}`

We are required to evaluate the expression:

`4y\text{ - 12}`

To do this, we simply substitute 3 for y into the expression and simplify

`\begin{gathered} =\text{ 4\lparen3\rparen - 12} \\ =\text{ 12 - 12} \\ =\text{ 0} \end{gathered}`

Hence, the expression evaluates to 0

Answer: 0
