Answer 1

When you need to evaluate an expression it means that you have to replace the variables with the given values for them and solve

The expression is

`12x-3y`

For x=-1/4 and y=3

Replace the given values for x and y in the formula and solve

`\begin{gathered} 12(-(1)/(4))-3\cdot(3) \\ -3-9=-12 \end{gathered}`
