Problem:

If x = -3 and y = 4x - 1, then y equals what number?


\quad \quad \quad \quad\tt{y = 4x - 1}


\quad \quad \quad \quad\tt{y = 4( - 3) - 1}


\quad \quad \quad \quad\tt{y = (- 12)- 1}


\quad \quad \quad \quad\tt{y = - 13}

Hence, The value of y is:


\quad \quad \quad \quad \boxed{\tt \color{green}{y = - 13}}

\huge\text{Hey there!}


\large\textsf{y = 4x - 1}


\large\text{If x= -3, then substitute it into the given equation}


\large\textsf{y = 4(-3) - 1}


\large\textsf{4(-3) = \boxed{\bf -12}}


\large\textsf{y = -12 - 1}


\large\textsf{-12 - 1 = y}


\large\textsf{-12 - 1 = \boxed{\bf -13}}


\boxed{\boxed{\large\textsf{Answer: \huge \bf y = -13}}}\huge\checkmark
