sqrt(3z+15)+7=z+6

3 z + 15 + 7 = z + 6

z = 7

Solution steps

3 z + 15 + 7 = z + 6

Remove square roots

3 z + 15 = z^{2} - 2 z + 1

Solve

3 z + 15 = z^{2} - 2 z + 1 : z = 7, z = - 2

z = 7, z = - 2

Verify Solutions:

z = 7

True

, z = - 2

False

The solution is

z = 7

4 = a + 5

x + 8 = 7 x

x^{2} = x + 1

27 - 2 x = x - 3

w = 9 w - 18
