Solve the Inequality for d d/2-1>=3

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

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

Add $1$ to both sides of the inequality.

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

Add $3$ and $1$ .

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

Multiply both sides by $2$ .

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

Simplify.

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

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

Rewrite the expression.

$d \geq 4 \cdot 2$

Simplify the right side.

Multiply $4$ by $2$ .

$d \geq 8$

The result can be shown in multiple forms.

Inequality Form:

$d \geq 8$
