$0.123+x=10.123+x=1\backslash \backslash$

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.

$0.123+x-0.123=1-0.123\backslash \; \backslash \; \backslash \; 0.123+x-0.123\backslash \; =\backslash \; 1-0.123$

$x=0.877\backslash \; \backslash \; \backslash \; x\backslash \; =\backslash \; 0.877$

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

Step 4: Check.

$0.123+0.877=10.123+0.877\backslash \; =\backslash \; 1$

$1=1\backslash \; \backslash \; \backslash \; 1\backslash \; =\backslash \; 1$. This is a true statement.

$x-0.044=3x-0.044=3\backslash \backslash$

Forme den Term nach $xx$ um indem du auf beiden Seiten $0.0440.044$ addierst.

$x=3.044x=3.044$
