Step-by-step explanation:
7(x + 6) = 42
<em>distributive property</em><em>: a(b + c) = ab + ac</em>
(7)(x) + (7)(6) = 42
7x + 42 = 42
<em>subtraction property of equality</em><em> (subtract 42 from both sides)</em>
7x + 42 - 42 = 42 - 42
7x = 0
<em>division property of equality </em><em> (divide both sides by 7)</em>
7x : 7 = 0 : 7
x = 0
