z + 3 - 3 z - 1 = 0

z = \frac{5 - 21}{2}

Solution steps

z + 3 - 3 z - 1 = 0

Remove square roots

4 z^{2} - 8 z + 4 = 12 z

Solve

4 z^{2} - 8 z + 4 = 12 z : z = \frac{5 + 21}{2}, z = \frac{5 - 21}{2}

z = \frac{5 + 21}{2}, z = \frac{5 - 21}{2}

Verify Solutions:

z = \frac{5 + 21}{2}

False

, z = \frac{5 - 21}{2}

True

The solution is

z = \frac{5 - 21}{2}

4 - x = x + 2

x - 1 + 2 - x = 1

21 + 4 x = x

x - 1 = 5 - x
