Problem: [tex]\bold{t+16=7}[/tex]
[ Step One ] Subtract 16 From Both Sides
[tex]\bold{t+16-16=7-16}[/tex]
[ Step Two ] Divide Both Sides By 3
[tex]\bold{\frac{3\left(k+7\right)}{3}=\frac{81}{3}}[/tex]
[ Step Two ] Simplify
[tex]\bold{k+7=27}[/tex]
[ Step Three ] Subtract 7 From Both Sides
[tex]\bold{k+7-7=27-7}[/tex]
[ Step Four ] Simplify
[tex]\bold{k=20}[/tex]
[tex]\bold{t=-9}[/tex]

Problem: [tex]\bold{\frac{w}{4}=-11}[/tex]
Note: [tex]\bold{Fraction \ Bar \ "/" \ Means \ The \ Same \ Thing \ As \ \div}[/tex]
[ Step One ] Multiply Both Sides By 4
[tex]\bold{\frac{4w}{4}=4\left(-11\right)}[/tex]
[ Step Two ] Simplify
[tex]\bold{w=-44}[/tex]
<><><><><><><>
Problem: [tex]\bold{81=3(k+7)}[/tex]
[ Step One ] Switch Sides
[tex]\bold{3\left(k+7\right)=81}[/tex]
[ Step Two ] Simplify
