Math Problem Statement
Solve the equation for all values of x.
open vertical bar, 4, x, minus, 4, close vertical bar, plus, 8, equals, 2, x
∣4x−4∣+8=
2x
Solution
The given equation is:
Step 1: Isolate the absolute value expression
Subtract 8 from both sides of the equation:
Step 2: Solve for both cases of the absolute value
The absolute value means that we need to solve two cases: one for when , and one for when .
Case 1: or
In this case, the absolute value is just , so the equation becomes:
Solve for :
Since we assumed in this case, the solution does not satisfy this condition and should be discarded.
Case 2: or
In this case, the absolute value becomes , so the equation becomes:
Solve for :
Since we assumed in this case, the solution does not satisfy this condition and should also be discarded.
Conclusion:
There is no solution to the given equation because none of the values of satisfy the original conditions.
