Solve for d d/2-1=3

$\frac{d}{2} - 1 = 3$

Step 1

Move all terms not containing $d$ to the right side of the equation.

Add $1$ to both sides of the equation.

$\frac{d}{2} = 3 + 1$

Add $3$ and $1$ .

$\frac{d}{2} = 4$

Step 2

Multiply both sides of the equation by $2$ .

$2 \frac{d}{2} = 2 \cdot 4$

Step 3

Simplify both sides of the equation.

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$2 \frac{d}{2} = 2 \cdot 4$

Rewrite the expression.

$d = 2 \cdot 4$

Simplify the right side.

Multiply $2$ by $4$ .

$d = 8$
