Solution for 12(z+4)-3(z-2)=4(z-1)+4(z-4) equation:


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

Reorder the terms:
12(4 + z) + -3(z + -2) = 4(z + -1) + 4(z + -4)
(4 * 12 + z * 12) + -3(z + -2) = 4(z + -1) + 4(z + -4)
(48 + 12z) + -3(z + -2) = 4(z + -1) + 4(z + -4)

Reorder the terms:
48 + 12z + -3(-2 + z) = 4(z + -1) + 4(z + -4)
48 + 12z + (-2 * -3 + z * -3) = 4(z + -1) + 4(z + -4)
48 + 12z + (6 + -3z) = 4(z + -1) + 4(z + -4)

Reorder the terms:
48 + 6 + 12z + -3z = 4(z + -1) + 4(z + -4)

Combine like terms: 48 + 6 = 54
54 + 12z + -3z = 4(z + -1) + 4(z + -4)

Combine like terms: 12z + -3z = 9z
54 + 9z = 4(z + -1) + 4(z + -4)

Reorder the terms:
54 + 9z = 4(-1 + z) + 4(z + -4)
54 + 9z = (-1 * 4 + z * 4) + 4(z + -4)
54 + 9z = (-4 + 4z) + 4(z + -4)

Reorder the terms:
54 + 9z = -4 + 4z + 4(-4 + z)
54 + 9z = -4 + 4z + (-4 * 4 + z * 4)
54 + 9z = -4 + 4z + (-16 + 4z)

Reorder the terms:
54 + 9z = -4 + -16 + 4z + 4z

Combine like terms: -4 + -16 = -20
54 + 9z = -20 + 4z + 4z

Combine like terms: 4z + 4z = 8z
54 + 9z = -20 + 8z

Solving
54 + 9z = -20 + 8z

Solving for variable 'z'.

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

Add '-8z' to each side of the equation.
54 + 9z + -8z = -20 + 8z + -8z

Combine like terms: 9z + -8z = 1z
54 + 1z = -20 + 8z + -8z

Combine like terms: 8z + -8z = 0
54 + 1z = -20 + 0
54 + 1z = -20

Add '-54' to each side of the equation.
54 + -54 + 1z = -20 + -54

Combine like terms: 54 + -54 = 0
0 + 1z = -20 + -54
1z = -20 + -54

Combine like terms: -20 + -54 = -74
1z = -74

Divide each side by '1'.
z = -74

Simplifying
z = -74
