Solve 3(y-1)=C

$$3 ( y - 1 ) = C$$

Solve for C

$$C=3\left(y-1\right)$$

Solution Steps

Use the distributive property to multiply 3 by y-1.

$$3y-3=C$$

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

$$C=3y-3$$

Solve for y

$$y=\frac{C+3}{3}$$

Steps for Solving Linear Equation

Use the distributive property to multiply 3 by y-1.

$$3y-3=C$$

Add 3 to both sides.

$$3y=C+3$$

Divide both sides by 3.

$$\frac{3y}{3}=\frac{C+3}{3}$$

Dividing by 3 undoes the multiplication by 3.

$$y=\frac{C+3}{3}$$

Divide C+3 by 3.

$$y=\frac{C}{3}+1$$
