\huge\text{Hey there!}

Question #1 ↓


\huge\boxed{\mathsf{3x = -9}}\\\huge\text{DIVIDE 3 to BOTH SIDES}\\\huge\boxed{\mathsf{(3x)/(3)=(-9)/(3)}}\\\huge\text{CANCEL out: }\huge\boxed{\mathsf{(3)/(3)}}\\\huge\text{KEEP: }\huge\boxed{\mathsf{(-9)/(3)}}\\\huge\boxed{\mathsf{x = (-9)/(3)}}\\\\\\\\\boxed{\mathsf{x = \bf -3}}

Question #2 ↓


\huge\boxed{\frak{{4x = -12}}}\\\huge\text{DIVIDE 4 to BOTH SIDES}\\\huge\boxed{\frak{(4x)/(4)= (-12)/(4)}}\\\huge\text{CANCEL out: }\boxed{\frak{(4)/(4)}}\\\huge\text{KEEP: }\boxed{\frak{(-12)/(4)}}}\\\huge\boxed{\frak{x = (-12)/(3)}}\\\\\\\\\huge\boxed{x = \bf -3}


\huge\boxed{\frak{-3 = -3}}\\\\\\\huge\boxed{\frak{Therefore, to\ answer\ your\ question...\ it\ is}}\\\huge\boxed{\frak{\bold{TRUE} \ because\ they\ are\ equivalent\ to\ each}}\\\huge\boxed{\frak{other}}


\huge\textsf{Good luck on your assignment \& enjoy your day!}\\\\\huge\boxed{\frak{Amphitrite1040:)}}
