Question

Evaluate −4x−y+4 when x=−1/4 and y=3.

Answer 1

Given:

• x = -1/4
• y = 3

To find: the value of -4x - y + 4.

Answer:

Let's substitute the given values of x and y into the expression.

$\sf -4\ \times\ \dfrac{-1}{4}\ -\ 3\ +\ 4\\\\\\=\ -1\ \times\ -1\ -\ 3\ +\ 4\\\\\\=\ 1\ -\ 3\ +\ 4\\\\\\=\ 1\ -\ 1\\\\\\=\ 0$

Therefore, the value of -4x - y + 4 when x = -1/4 and y = 3 is 0.

Hope it helps. :)
