    Answer:

    just as you can add the same value to each side of an equation without changing the meaning of the equation, you can subtract the same value from each side of an equation.

    by-step explanation:

    x+7=42

    Since 7 is being added to the variable, subtract 7 to isolate the variable.

    To keep the equation balanced, subtract 7 from both sides of the equation.

    x+7=42

    -7 over x+0

    -7 over 35

    so answer is 35
