Solve a_{18}-a_{2}=40

$$a _ { 18 } - a _ { 2 } = 40$$

Solve for a_2

$$a_{2}=a_{18}-40$$

Steps for Solving Linear Equation

Subtract a_{18} from both sides.

$$-a_{2}=40-a_{18}$$

Divide both sides by -1.

$$\frac{-a_{2}}{-1}=\frac{40-a_{18}}{-1}$$

Dividing by -1 undoes the multiplication by -1.

$$a_{2}=\frac{40-a_{18}}{-1}$$

Divide 40-a_{18} by -1.

$$a_{2}=a_{18}-40$$

Solve for a_18

$$a_{18}=a_{2}+40$$

Solution Steps

Add a_{2} to both sides.

$$a_{18}=40+a_{2}$$
