Question

$$7inl+13=90$$

Solve for l

$l=\frac{-11i}{n}$
$n\neq 0$

Steps for Solving Linear Equation

Subtract $13$ from both sides.

$$7inl=90-13$$

Subtract $13$ from $90$ to get $77$.

$$7inl=77$$

Divide both sides by $7in$.

$$\frac{7inl}{7in}=\frac{77}{7in}$$

Dividing by $7in$ undoes the multiplication by $7in$.

$$l=\frac{77}{7in}$$

Divide $77$ by $7in$.

$$l=\frac{-11i}{n}$$

Show Solution

Solve for n

$n=\frac{-11i}{l}$
$l\neq 0$

Steps for Solving Linear Equation

Subtract $13$ from both sides.

$$7inl=90-13$$

Subtract $13$ from $90$ to get $77$.

$$7inl=77$$

The equation is in standard form.

$$7iln=77$$

Divide both sides by $7il$.

$$\frac{7iln}{7il}=\frac{77}{7il}$$

Dividing by $7il$ undoes the multiplication by $7il$.

$$n=\frac{77}{7il}$$

Divide $77$ by $7il$.

$$n=\frac{-11i}{l}$$
