Problem: $\bold{t+16=7}$

[ Step One ] Subtract 16 From Both Sides

$\bold{t+16-16=7-16}$

[ Step Two ] Divide Both Sides By 3

$\bold{\frac{3\left(k+7\right)}{3}=\frac{81}{3}}$

[ Step Two ] Simplify

$\bold{k+7=27}$

[ Step Three ] Subtract 7 From Both Sides

$\bold{k+7-7=27-7}$

[ Step Four ] Simplify

$\bold{k=20}$

$\bold{t=-9}$

Problem: $\bold{\frac{w}{4}=-11}$

Note: $\bold{Fraction \ Bar \ "/" \ Means \ The \ Same \ Thing \ As \ \div}$

[ Step One ] Multiply Both Sides By 4

$\bold{\frac{4w}{4}=4\left(-11\right)}$

[ Step Two ] Simplify

$\bold{w=-44}$

Problem: $\bold{81=3(k+7)}$

[ Step One ] Switch Sides

$\bold{3\left(k+7\right)=81}$

[ Step Two ] Simplify
