The little phrase (eight times) tells us to multiply s times 8: [tex]\mathsf{8s}[/tex].
The phrase (the difference of) tells us to subtract 3 minus s: [tex]\mathsf{s-3}[/tex].
Now, the problem also tells us to multiply 8 times 3-s: [tex]\mathsf{8(s-3)}[/tex].
Notice I put parentheses around 3-s. This tells us to multiply 8 times both terms - 3 and -s. [tex]\star[/tex]
Finally, this expression is 64. All of our hard work results in the following equation: ✨ [tex]\bigstar\underline{\boxed{\mathrm{8(s-3)=64}}}[/tex] [tex]\star[/tex]
Hope this helped you out, ask in comments if any queries arise.
