To start, first just substitute 2x - 3 for each occurance of "x" in the definition. Then solve for x. I.e, |2x-3| = 2x-3 when 2x-3 > 0, |2x-3| = -(2x - 3) when 2x - 3 < 0.
Can anyone please hammer out this idea of absolute value for me. Please.
I know its relatively simple but I just cant seem to get the ideas into my head. I know what it looks like graphically using a graphing utility but once I come to actually solve it by hand, I have no idea what to do
I love this question. It is at the very base of a great deal of mathematics.
The absolute value of x, is the distance is from .
So we can see is three units from zero so .
So look at this question: Solve .
O.K. What number is two units from zero? Well of course that answer is .
So solve this system .
