SOLUTION: Solve each absolute value equation: A.) |x|-3=10 B.) |x-3|=10 C.)4|2x+1|-5=3 ----- I am getting these answer: A.) x=13 or x=-7 B.) x=-7 or x=13 C.) x=3/2 or -5/2 A and

Question 176550: Solve each absolute value equation:
A.) |x|-3=10
B.) |x-3|=10
C.)4|2x+1|-5=3
-----
I am getting these answer:
A.) x=13 or x=-7
B.) x=-7 or x=13
C.) x=3/2 or -5/2
A and B seem to work, but C is not adding up.
Thank you!
