x+1=2y

Tilføj 2y på begge sider. Ethvert tal plus nul giver tallet selv.

x=2y-1

Subtraher 1 fra begge sider.

-2y+1=-x

Subtraher x fra begge sider. Ethvert tal trukket fra nul giver tallets negation.

-2y=-x-1

Subtraher 1 fra begge sider.

\frac{-2y}{-2}=\frac{-x-1}{-2}

Divider begge sider med -2.

y=\frac{-x-1}{-2}

Division med -2 annullerer multiplikationen med -2.

y=\frac{x+1}{2}

Divider -x-1 med -2.
