\huge\text{Hey there!}


\large\text{-4x + 10 = 50}


\large\text{SUBTRACT by 10 to BOTH SIDES}


\large\text{-4x + 10 - 10 = 50 - 10}


\large\text{Cancel out: 10 - 10 because that gives you 0}


\large\text{Keep: 50 - 10 because it helps us solve for your x value}


\large\text{50 - 10 = 40}


\large\text{New equation: -4x = 40}


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


\mathsf{(-4x)/(4)=(40)/(-4)}


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


\large\text{Keep: }\mathsf{(-40)/(4)}\large\text{ because it helps find x}


\mathsf{(-40)/(4)= -40/4 \rightarrow \bf -10}


\boxed{\boxed{\large\text{Answer: \bf x = -10}}}\huge\checkmark


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