Step 1.1

Subtract $b$ from both sides of the equation.

$b + d - c - b = d - c$

Step 1.2

Combine the opposite terms in $b + d - c - b$ .

Step 1.2.1

Subtract $b$ from $b$ .

$d - c + 0 = d - c$

Step 1.2.2

Add $d - c$ and $0$ .

$d - c = d - c$

Step 2

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

Step 2.1

Add $c$ to both sides of the equation.

$d = d - c + c$

Step 2.2

Combine the opposite terms in $d - c + c$ .

Tap for more steps...

Step 2.2.1

Add $- c$ and $c$ .

$d = d + 0$

Step 2.2.2

Add $d$ and $0$ .

$d = d$

Step 3

The variable $b$ got canceled.
