[tex]\huge\textbf{Equation/Question:}[/tex]
[tex]\mathbf{7n - (4n - 3)}[/tex]
[tex]\huge\textbf{Convert equation/question to:}[/tex]
[tex]\mathbf{= 7n - 1(4n - 3)}[/tex]
[tex]\huge\textbf{Solving the equation/question:}[/tex]
[tex]\mathbf{= 7n - 1(4n) - 1(-3)}[/tex]
[tex]\mathbf{= 7n - 4n + 3}[/tex]
[tex]\huge\textbf{Combine the like terms:}[/tex]
[tex]\mathbf{= (7n - 4n) + 3}[/tex]
[tex]\mathbf{= 7n - 4n + 3}[/tex]
[tex]\mathbf{= 3n + 3}[/tex]
[tex]\huge\textbf{Therefore, your answer should be:}[/tex]
[tex]\huge\boxed{\frak{3n + 3}}\huge\checkmark[/tex]
