Given:
To find: the value of -4x - y + 4.
Answer:
Let's substitute the given values of x and y into the expression.
[tex]\sf -4\ \times\ \dfrac{-1}{4}\ -\ 3\ +\ 4\\\\\\=\ -1\ \times\ -1\ -\ 3\ +\ 4\\\\\\=\ 1\ -\ 3\ +\ 4\\\\\\=\ 1\ -\ 1\\\\\\=\ 0[/tex]
Therefore, the value of -4x - y + 4 when x = -1/4 and y = 3 is 0.
Hope it helps. :)
