\huge\text{Hey there!}


\mathsf{4(x + 3) = 8}\\\mathsf{\rightarrow 4(1x + 3) = 8}\\\mathsf{\rightarrow 4(x) + 4(3) = 8}\\\mathsf{\rightarrow 4(1x) + 4(3) = 8}\\\mathsf{\rightarrow 4x + 12 = 8}\\\\\large\text{SUBTRACT 8 to BOTH SIDES}\\\mathsf{\rightarrow 4x + 12 - 12 = 8 - 12}\\\\\large\text{SIMPLIFY IT!}\\\mathsf{\rightarrow 4x = 8 - 12}\\\mathsf{\rightarrow 4x = -4}\\\\\large\text{DIVIDE 4 to BOTH SIDES}\\\mathsf{\rightarrow (4x)/(4)= (-4)/(4)}


\large\text{SIMPLIFY IT!}\\\mathsf{\rightarrow x = (-4)/(4)}\\\mathsf{\rightarrow x = -1}\\\\\\\huge\text{Therefore, your answer should be: \boxed{\mathsf{x = -1}}}\huge\checkmark
