Respuesta :

Step 2:

[tex]10x-30=7x[/tex]

Step 3: To balance an equation using the same mathematical operation on both sides. In the given case to get all terms with variable x on one side of the equation you use the subtraction property: subtract 7x in both sides of the equation:

[tex]\begin{gathered} 10x-7x-30=7x-7x \\ \\ 3x-30=0 \end{gathered}[/tex]

Answer C) subtraction property
