\bold{t+16=7}

\bold{\frac{w}{4}=-11}

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

<><><><><><><>

Answers:

\boxed{\bold{t=-9}}

\boxed{\bold{w=-44}}

\boxed{\bold{k=20}}

<><><><><><><>

Explanation: \downarrow\downarrow\downarrow

<><><><><><><>

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

<><><><><><><>

\bold{\rightarrow Mordancy \leftarrow}
