Solve 1/-11=1/-7+1/do

$$\frac { 1 } { - 11 } = \frac { 1 } { - 7 } + \frac { 1 } { d o }$$

Solve for d

$$d=\frac{77}{4o}$$

$$o\neq 0$$

Steps for Solving Linear Equation

Variable d cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 77do, the least common multiple of -11,-7,do.

$$-7do=-11do+77$$

Add 11do to both sides.

$$-7do+11do=77$$

Combine -7do and 11do to get 4do.

$$4do=77$$

The equation is in standard form.

$$4od=77$$

Divide both sides by 4o.

$$\frac{4od}{4o}=\frac{77}{4o}$$

Dividing by 4o undoes the multiplication by 4o.

$$d=\frac{77}{4o}$$

Variable d cannot be equal to 0.

$$d=\frac{77}{4o}\text{, }d\neq 0$$

Solve for o

$$o=\frac{77}{4d}$$

$$d\neq 0$$

Steps for Solving Linear Equation

Variable o cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 77do, the least common multiple of -11,-7,do.

$$-7do=-11do+77$$

Add 11do to both sides.

$$-7do+11do=77$$

Combine -7do and 11do to get 4do.

$$4do=77$$

Divide both sides by 4d.

$$\frac{4do}{4d}=\frac{77}{4d}$$

Dividing by 4d undoes the multiplication by 4d.

$$o=\frac{77}{4d}$$

Variable o cannot be equal to 0.

$$o=\frac{77}{4d}\text{, }o\neq 0$$
