Step-by-step explanation:
1. |x-3|=7 and x-3=7
<em>Absoulte rules.</em>
<em>x-3=-7 and x-3=7</em>
<em>Add 3 both sides.</em>
<em>x-3+3=-7+3</em>
<em>Simplify.</em>
<em>-7+3=-4</em>
<em>x=-4</em>
<em>x-3=7</em>
<em>Add by 3 both sides.</em>
<em>x-3+3=7+3=10</em>
<em>x=10</em>
<em>X=-4, and X=10 is the correct answer.</em>
