Solve d=3(t+3)

$$d = 3 ( t + 3 )$$

Solve for t

$$t=\frac{d-9}{3}$$

Steps for Solving Linear Equation

Use the distributive property to multiply 3 by t+3.

$$d=3t+9$$

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

$$3t+9=d$$

Subtract 9 from both sides.

$$3t=d-9$$

Divide both sides by 3.

$$\frac{3t}{3}=\frac{d-9}{3}$$

Dividing by 3 undoes the multiplication by 3.

$$t=\frac{d-9}{3}$$

Divide d-9 by 3.

$$t=\frac{d}{3}-3$$

Solve for d

$$d=3\left(t+3\right)$$

Solution Steps

Use the distributive property to multiply 3 by t+3.

$$d=3t+9$$
