`\large\boxed{\mathsf{13 - 2x^1 = 9}}\\\\\large\boxed{\mathsf{\rightarrow 13 - 2x = 9}}\\\\\large\boxed{\rightarrow \mathsf{-2x + 13 = 9}}\\\\\large\boxed{\textbf{SUBTRACT 13 to BOTH SIDES}}\\\\\large\boxed{\mathsf{-2x + 13 - 13 = 9 - 13}}\\\\\large\boxed{\textbf{CANCEL out: 13 - 13 because it gives you 0}}\\\large\boxed{\textbf{KEEP: 9 - 13 because it help solve for the x-value}}\\\\\large\boxed{\textbf{NEW EQUATION: -2x = 9 - 13}}\\\large\boxed{\textbf{SIMPLIFY IT!}}\\\\\large\boxed{\mathsf{-2x = -4}}`

`\large\boxed{\textbf{DIVIDE -2 to BOTH SDES}}\\\\\large\boxed{\mathsf{(-2x)/(-2) = (-4)/(-2)}}\\\\\large\boxed{\textbf{CANCEL out: } \mathbf{(-2)/(-2)} \textbf{ because it gives you 1}}\\\\\large\boxed{\textbf{KEEP: } \bf (-4)/(-2) \textbf{ because it gives you the value of x}}\\\\\large\boxed{\textbf{NEW EQUATION: } \mathbf{x= (-4)/(-2)}}\\\\\boxed{\large\textsf{SIMPLIFY IT!}}\\\\\large\boxed{\textbf{x = 2}}`

`\huge\text{Therefore, your answer is: \boxed{\mathsf{x = 2}}}\huge\checkmark`
