[tex]\large\textsf{x + 3 = 15}[/tex]
[tex]\huge\text{SUBTRACT 3 to BOTH SIDES}[/tex]
[tex]\large\textsf{x + 3 - 3 = 15 - 3}[/tex]
[tex]\large\textsf{CANCEL out: 3 - 3 because that gives you 0}[/tex]
[tex]\large\textsf{KEEP: 15 - 3 because it helps solve for x}[/tex]
[tex]\large\textsf{15 - 3 = x}[/tex]
[tex]\boxed{\boxed{\large\textsf{Answer: \huge \bf x = 12}}}\huge\checkmark[/tex]
