\huge\text{Hey there!}


\large\textsf{-4x + 1 = 21}


\large\text{SUBTRACT 1 to BOTH SIDES}


\large\textsf{-4x + 1 - 1 = 21 - 1}


\large\text{CANCEL out: 1 - 1 because that gives you 0 }


\large\text{KEEP: 21 - 1 because that helps solve for x}


\large\text{21 - 1 = \bf 20}


\large\text{New equation: \textsf{ -4x = 20}}


\large\text{DIVIDE -4 to BOTH SIDES}


\mathsf{(-4x)/(-4)=(20)/(-4)}


\large\text{CANCEL out: }\mathsf{(-4)/(-4)}\large\text{ because that gives you 1}


\large\text{KEEP: }\mathsf{(20)/(-4)}\large\text{ because it gives you the value of x}


\mathsf{x = (20)/(-4)}


\mathsf{(20)/(-4)= 20/ -4=\bf -5}


\boxed{\boxed{\large\text{Answer: \huge \bf x = -5}}}\huge\checkmark


\text{Good luck on your assignment and enjoy your day!}
