Solution for 10[z-(9z+18)+10]=5(z+1) equation:


Simplifying
10[z + -1(9z + 18) + 10] = 5(z + 1)

Reorder the terms:
10[z + -1(18 + 9z) + 10] = 5(z + 1)
10[z + (18 * -1 + 9z * -1) + 10] = 5(z + 1)
10[z + (-18 + -9z) + 10] = 5(z + 1)

Reorder the terms:
10[-18 + 10 + z + -9z] = 5(z + 1)

Combine like terms: -18 + 10 = -8
10[-8 + z + -9z] = 5(z + 1)

Combine like terms: z + -9z = -8z
10[-8 + -8z] = 5(z + 1)
[-8 * 10 + -8z * 10] = 5(z + 1)
[-80 + -80z] = 5(z + 1)

Reorder the terms:
-80 + -80z = 5(1 + z)
-80 + -80z = (1 * 5 + z * 5)
-80 + -80z = (5 + 5z)

Solving
-80 + -80z = 5 + 5z

Solving for variable 'z'.

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