Solve an=-63+left(n-1right)4

$$an = -63+ \left( n-1 \right) 4$$

Solve for a

$$a=4-\frac{67}{n}$$

$$n\neq 0$$

Steps for Solving Linear Equation

Use the distributive property to multiply n-1 by 4.

$$an=-63+4n-4$$

Subtract 4 from -63 to get -67.

$$an=-67+4n$$

The equation is in standard form.

$$na=4n-67$$

Divide both sides by n.

$$\frac{na}{n}=\frac{4n-67}{n}$$

Dividing by n undoes the multiplication by n.

$$a=\frac{4n-67}{n}$$

Divide -67+4n by n.

$$a=4-\frac{67}{n}$$

Solve for n

$$n=-\frac{67}{a-4}$$

$$a\neq 4$$

Steps for Solving Linear Equation

Use the distributive property to multiply n-1 by 4.

$$an=-63+4n-4$$

Subtract 4 from -63 to get -67.

$$an=-67+4n$$

Subtract 4n from both sides.

$$an-4n=-67$$

Combine all terms containing n.

$$\left(a-4\right)n=-67$$

Divide both sides by a-4.

$$\frac{\left(a-4\right)n}{a-4}=-\frac{67}{a-4}$$

Dividing by a-4 undoes the multiplication by a-4.

$$n=-\frac{67}{a-4}$$
