\huge\text{Hey there!}


\large\textsf{2x + 12 = 40}


\large\text{SUBTRACT 12 to BOTH SIDES}


\large\textsf{2x + 12 - 12 = 40 - 12}


\large\text{CANCEL out: \textsf{12 - 12} because that gives you \textsf{0}}


\large\text{KEEP: \textsf{40 - 12} because that helps solve for \textsf{x}}


\large\textsf{40 - 12 = \bf 28}


\large\text{New EQUATION: \textsf{2x = 28}}


\large\text{DIVIDE 2 to BOTH SIDES}


\mathsf{(2x)/(2)=(28)/(2)}


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


\large\text{KEEP: }\mathsf{(28)/(2)}\large\text{ because gives you the value of x}


\mathsf{x = (28)/(2)}


\boxed{\boxed{\large\textsf{Answer: \bf \huge x = 14}}}\huge\checkmark
