The first step in solving the equation is dividing both sides by 8:
[tex]100=8(4t-5)[/tex][tex]\frac{100}{8}=4t-5[/tex][tex]12.5=4t-5[/tex]Adding 4 to both sides gives
[tex]12.5+5=4t[/tex][tex]17.5=4t[/tex]Finally, dividing both sides by 4 gives
[tex]\frac{17.5}{4}=t[/tex][tex]t=4.375[/tex]which is our answer!
