Solution for abs(z+4)=3*abs(z-4) equation:


Simplifying
abs(z + 4) = 3abs(z + -4)

Reorder the terms:
abs(4 + z) = 3abs(z + -4)
(4 * abs + z * abs) = 3abs(z + -4)
(4abs + absz) = 3abs(z + -4)

Reorder the terms:
4abs + absz = 3abs(-4 + z)
4abs + absz = (-4 * 3abs + z * 3abs)
4abs + absz = (-12abs + 3absz)

Solving
4abs + absz = -12abs + 3absz

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '12abs' to each side of the equation.
4abs + 12abs + absz = -12abs + 12abs + 3absz

Combine like terms: 4abs + 12abs = 16abs
16abs + absz = -12abs + 12abs + 3absz

Combine like terms: -12abs + 12abs = 0
16abs + absz = 0 + 3absz
16abs + absz = 3absz

Add '-3absz' to each side of the equation.
16abs + absz + -3absz = 3absz + -3absz

Combine like terms: absz + -3absz = -2absz
16abs + -2absz = 3absz + -3absz

Combine like terms: 3absz + -3absz = 0
16abs + -2absz = 0

Factor out the Greatest Common Factor (GCF), '2abs'.
2abs(8 + -1z) = 0

Ignore the factor 2.

Subproblem 1

Set the factor 'abs' equal to zero and attempt to solve: Simplifying abs = 0 Solving abs = 0 Move all terms containing a to the left, all other terms to the right. Simplifying abs = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(8 + -1z)' equal to zero and attempt to solve: Simplifying 8 + -1z = 0 Solving 8 + -1z = 0 Move all terms containing a to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + -1z = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -1z = 0 + -8 -1z = 0 + -8 Combine like terms: 0 + -8 = -8 -1z = -8 Add 'z' to each side of the equation. -1z + z = -8 + z Combine like terms: -1z + z = 0 0 = -8 + z Simplifying 0 = -8 + z The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
