[tex]\huge\text{Hey there!}[/tex]
[tex]\large\text{Question reads: }\large\textsf{When I was 6 my sister was 3, Now I am 70. How old}\\\large\textsf{is my little sister? }[/tex]
[tex]\large\text{First thing first you can figure out how old she is if you do the}\\\large\text{correct way to solve it. We will label \underline{s} as her previous age to}\\\large\text{find her current age.}\\\\\\\textsf{6 - s = 3}\\\\\textsf{-s + 6 = 3}\\\\\text{SUBTRACT 6 to BOTH SIDES}\\\large\textsf{-s + 6 - 6 = 3 - 6}\\\text{CANCEL out: 6 - 6 because it gives you 0}\\\large\text{KEEP: 3 - 6 because it help solve for the s-value}\\\\\large\text{NEW EQUATION: \textsf{-s = 3 - 6}}\\\large\text{SIMPLIFY IT!}[/tex]
[tex]\textsf{-s = -3}\\\\\large\text{DIVIDE -1 to BOTH SIDES}\\\\\mathsf{\dfrac{-s}{-1} = \dfrac{-3}{-1}}\\\\\mathsf{\rightarrow \dfrac{-1}{-1}s = \dfrac{-3}{-1}}\\\\\large\text{CANCEL out: }\rm{\dfrac{-1}{-1}}\large\text{ bevause it gives you 1}\\\large\text{KEEP: }\rm{\dfrac{-3}{-1}}\large\text{ because it gives you the s-va;ue}\\\\\large\text{NEW EQUATION: s = }\rm{\dfrac{-3}{-1}}\\\\\large\text{SIMPLIFY IT!}\\\\\textsf{s = 3}[/tex]
[tex]\large\textbf{Now, we know how many years your sister is younger than}\\\large\textbf{you. She's about 3 years under. We can subtract 3 from}\\\large\textbf{from 70 to find her exact current age. }\\\\\large\text{EQUATION: \textsf{70 - 3 = s}}\\\\\textsf{SIMPLIFY IT \& YOU HAVE YOUR FINAL RESULT!}\\\\\large\text{Start at 70 \& go back 3 spaces to your right. You should have}\\\large\text{landed on \bf 67.}\\\\\\\huge\text{Thus, your answer is: \boxed{\mathsf{67}}}\huge\checkmark[/tex]
[tex]\huge\text{Good luck on your assignment \& enjoy your day!}[/tex]
