Solve each absolute value equation:
4-3|x - 2|= -8
Isolate the absolute value on the
left:
Subtract 4 from both sides:
-3(x - 2| = -8-4
-3|x - 2| = -12
Divide both sides by -3
|x - 2| = (-12)/(-3)
|x - 2| = 4
To solve equations of the form
|expression| = A
1. If A is negative there is no solution.
2. If A is 0, solve the equation expression = 0
3. if A is positive, solve both equations
expression = A and expression = -A
and get two solutions
Yours is case 3:
|x - 2| = 4
so we solve both equations:
x - 2 = 4 x - 2 = -4
x = 6 x = -2
Those are the two solutions.
