Solution for Zz-2(z+1)=3z-(20+5z) equation:


Simplifying
Zz + -2(z + 1) = 3z + -1(20 + 5z)

Reorder the terms:
zZ + -2(1 + z) = 3z + -1(20 + 5z)
zZ + (1 * -2 + z * -2) = 3z + -1(20 + 5z)
zZ + (-2 + -2z) = 3z + -1(20 + 5z)

Reorder the terms:
-2 + -2z + zZ = 3z + -1(20 + 5z)
-2 + -2z + zZ = 3z + (20 * -1 + 5z * -1)
-2 + -2z + zZ = 3z + (-20 + -5z)

Reorder the terms:
-2 + -2z + zZ = -20 + 3z + -5z

Combine like terms: 3z + -5z = -2z
-2 + -2z + zZ = -20 + -2z

Add '2z' to each side of the equation.
-2 + -2z + 2z + zZ = -20 + -2z + 2z

Combine like terms: -2z + 2z = 0
-2 + 0 + zZ = -20 + -2z + 2z
-2 + zZ = -20 + -2z + 2z

Combine like terms: -2z + 2z = 0
-2 + zZ = -20 + 0
-2 + zZ = -20

Solving
-2 + zZ = -20

Solving for variable 'z'.

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

Add '2' to each side of the equation.
-2 + 2 + zZ = -20 + 2

Combine like terms: -2 + 2 = 0
0 + zZ = -20 + 2
zZ = -20 + 2

Combine like terms: -20 + 2 = -18
zZ = -18

Divide each side by 'Z'.
z = -18Z-1

Simplifying
z = -18Z-1
