    Addition property of equality is used

    Solution:

    Given that,

    We have to find the property of equality or congruence that justifies going from the first statement to the second statement

    Given is:

    3a – 6 = 54

    3a = 60

    It is clear that, addition property of equality is used

    The property that states that if you add the same number to both sides of an equation, the sides remain equal

    The equation remains to be true, if we add or subtract same number on both sides of equation

    Therefore,

    3a – 6 = 54

    Add 6 on both sides of equation

    3a – 6 + 6 = 54 + 6

    3a = 54 + 6

    3a = 60

    Thus addition property of equality is used
