$\begin{array}{l}0.123+x=1\\ \end{array}$

Step 1: Not applicable. There are no like-terms on each side of the equality sign.

Step 2: Collect and combine like-terms of equations on opposite sides of the equality sign using the inverse operation. Variable terms are on the left-hand-side of the equality sign.

$0.123+x-0.123=1-0.123$

$x=0.877$

Step 3: Not applicable. The factor of the variable term is 1.

Step 4: Check.

$0.123+0.877=1$

$1=1$. This is a true statement.

$\begin{array}{l}x-0.044=3\\ \end{array}$

Forme den Term nach $x$ um indem du auf beiden Seiten $0.044$ addierst.

$x=3.044$
