[tex]\large\textsf{2x + 12 = 40}[/tex]
[tex]\large\text{SUBTRACT 12 to BOTH SIDES}[/tex]
[tex]\large\textsf{2x + 12 - 12 = 40 - 12}[/tex]
[tex]\large\text{CANCEL out: \textsf{12 - 12} because that gives you \textsf{0}}[/tex]
[tex]\large\text{KEEP: \textsf{40 - 12} because that helps solve for \textsf{x}}[/tex]
[tex]\large\textsf{40 - 12 = \bf 28}[/tex]
[tex]\large\text{New EQUATION: \textsf{2x = 28}}[/tex]
[tex]\large\text{DIVIDE 2 to BOTH SIDES}[/tex]
[tex]\mathsf{\dfrac{2x}{2}=\dfrac{28}{2}}[/tex]
[tex]\large\text{CANCEL out: }\mathsf{\dfrac{2}{2}}\large\text{ because that gives you 1}[/tex]
[tex]\large\text{KEEP: }\mathsf{\dfrac{28}{2}}\large\text{ because gives you the value of x}[/tex]
[tex]\mathsf{x = \dfrac{28}{2}}[/tex]
