For what value of x, is |x – 3| + |x + 1| + |x| = 10?  Choose the correct choice from the following choices:	A) 0	B) 3	C) -3	D) 4	E) -2
There are 3 transition points: -1, 0, 3   When x &gt; 3,   |x−3|+|x+1|+|x|=10|   x−3+x+1+x=10   x = 4   Satisfies   When 0 &lt; x &lt; 3   |x−3|+|x+1|+|x|=10   −(x−3)+(x+1)+x=10   x = 6 (Not possible since 0 &lt; x &lt; 3)   When -1 &lt; x &lt; 0   |x−3|+|x+1|+|x|=10   −(x−3)+−(x+1)+x=10   x = -8 (Not possible since -1 &lt; x &lt; 0)   When x &lt; -1   |x−3|+|x+1|+|x|=10   -(x - 3) - (x+1) - x = 10   x = -8/3   Satisfies   ANSWER:4
