\huge\text{Hey there!}


\large\text{x = 3}


\large\textsf{Option A.}\downarrow\\\\\mathsf{x + 4 = 7}\\\mathsf{x = 3}\\\mathsf{3+4=7}\\\mathsf{3+4 =\bf 7}\\\mathsf{7 = 7}\\\\\\\large\text{Option A. could possibly be your answer}\checkmark


\large\textsf{Option B. }\downarrow\\\\\mathsf{(x)/(9)=3}\\\\\mathsf{x = 3}\\\\\mathsf{(3)/(9)=3}\\\\\mathsf{(3)/(9)= (1)/(3)=\bf 0.333333}\\\\\mathsf{0.333333\\eq 3}\\\\\large\text{Option B. is NOT your possible answer}


\large\textsf{Option C. }\downarrow\\\mathsf{5-x =2}\\\mathsf{x = 3}\\\mathsf{5-3=2}\\\mathsf{5-3=\bf 2}\\\mathsf{2=2}\\\\\large\text{Option C. could possibly be your answer}\checkmark


\large\textsf{Option D. }\downarrow\\\\\mathsf{8x = 32}\\\mathsf{x =3}\\\mathsf{8(3)=\bf 24}\\\mathsf{24\\eq 32}\\\\\large\text{Option D. is NOT your possible answer}


\large\textsf{Option E. }\downarrow\\\mathsf{x - 10=7}\\\mathsf{x =3}\\\mathsf{3-10=7}\\\mathsf{3-10=\bf -7}\\\mathsf{-7\\eq7}\\\\\large\text{Option E. is NOT your possible answer}


\boxed{\large\text{Answer: \boxed{\large\text{\bf Option A. x + 4 = 7 \& Option C. 5 - x = 2}}}}\huge\checkmark
