Solution for 10(z+1)-3(z-1)=3(z-4)+3(z-2) equation: 


Simplifying
10(z + 1) + -3(z + -1) = 3(z + -4) + 3(z + -2)

Reorder the terms:
10(1 + z) + -3(z + -1) = 3(z + -4) + 3(z + -2)
(1 * 10 + z * 10) + -3(z + -1) = 3(z + -4) + 3(z + -2)
(10 + 10z) + -3(z + -1) = 3(z + -4) + 3(z + -2)

Reorder the terms:
10 + 10z + -3(-1 + z) = 3(z + -4) + 3(z + -2)
10 + 10z + (-1 * -3 + z * -3) = 3(z + -4) + 3(z + -2)
10 + 10z + (3 + -3z) = 3(z + -4) + 3(z + -2)

Reorder the terms:
10 + 3 + 10z + -3z = 3(z + -4) + 3(z + -2)

Combine like terms: 10 + 3 = 13
13 + 10z + -3z = 3(z + -4) + 3(z + -2)

Combine like terms: 10z + -3z = 7z
13 + 7z = 3(z + -4) + 3(z + -2)

Reorder the terms:
13 + 7z = 3(-4 + z) + 3(z + -2)
13 + 7z = (-4 * 3 + z * 3) + 3(z + -2)
13 + 7z = (-12 + 3z) + 3(z + -2)

Reorder the terms:
13 + 7z = -12 + 3z + 3(-2 + z)
13 + 7z = -12 + 3z + (-2 * 3 + z * 3)
13 + 7z = -12 + 3z + (-6 + 3z)

Reorder the terms:
13 + 7z = -12 + -6 + 3z + 3z

Combine like terms: -12 + -6 = -18
13 + 7z = -18 + 3z + 3z

Combine like terms: 3z + 3z = 6z
13 + 7z = -18 + 6z

Solving
13 + 7z = -18 + 6z

Solving for variable 'z'.

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

Add '-6z' to each side of the equation.
13 + 7z + -6z = -18 + 6z + -6z

Combine like terms: 7z + -6z = 1z
13 + 1z = -18 + 6z + -6z

Combine like terms: 6z + -6z = 0
13 + 1z = -18 + 0
13 + 1z = -18

Add '-13' to each side of the equation.
13 + -13 + 1z = -18 + -13

Combine like terms: 13 + -13 = 0
0 + 1z = -18 + -13
1z = -18 + -13

Combine like terms: -18 + -13 = -31
1z = -31

Divide each side by '1'.
z = -31

Simplifying
z = -31
