Solve D=(6a-1)*2

$$D = ( 6 a - 1 ) \times 2$$

Solve for a

$$a=\frac{D+2}{12}$$

Steps for Solving Linear Equation

Use the distributive property to multiply 6a-1 by 2.

$$D=12a-2$$

Swap sides so that all variable terms are on the left hand side.

$$12a-2=D$$

Add 2 to both sides.

$$12a=D+2$$

Divide both sides by 12.

$$\frac{12a}{12}=\frac{D+2}{12}$$

Dividing by 12 undoes the multiplication by 12.

$$a=\frac{D+2}{12}$$

Divide D+2 by 12.

$$a=\frac{D}{12}+\frac{1}{6}$$

Solve for D

$$D=12a-2$$

Solution Steps

Use the distributive property to multiply 6a-1 by 2.

$$D=12a-2$$
