\huge\text{Hey there!}


\large\text{If y = -4 then SUBSTITUTE it into the EQUATION}


\large\text{-4 = 2x + 2}


\large\text{TURN the EQUATION}


\large\text{2x + 2 = -4}


\large\text{SUBTRACT by 2 to BOTH SIDES}


\large\text{2x + 2 - 2 = -4 - 2}


\large\text{CANCEL out: 2 - 2 because that gives you 0}


\large\text{Keep: -4 - 2 because it helps us solve for x}


\large\text{2x = -6}


\large\text{DIVIDE by 2 to BOTH SIDES }


\mathsf{(2x)/(2)=(-6)/(2)}


\large\text{CANCEL out: }\mathsf{(2)/(2)}
\large\text{because that gives you 1}


\large\text{KEEP: }\mathsf{(-6)/(2)}
\large\text{because it gives us the value of x }


\boxed{\boxed{\large\text{Answer: \bf x = -3}}}\huge\checkmark\\\\\boxed{(-3,-4)}
