Solution for 7(z+2)-2(z-2)=2(z-4)+2(z-3) equation:


Simplifying
7(z + 2) + -2(z + -2) = 2(z + -4) + 2(z + -3)

Reorder the terms:
7(2 + z) + -2(z + -2) = 2(z + -4) + 2(z + -3)
(2 * 7 + z * 7) + -2(z + -2) = 2(z + -4) + 2(z + -3)
(14 + 7z) + -2(z + -2) = 2(z + -4) + 2(z + -3)

Reorder the terms:
14 + 7z + -2(-2 + z) = 2(z + -4) + 2(z + -3)
14 + 7z + (-2 * -2 + z * -2) = 2(z + -4) + 2(z + -3)
14 + 7z + (4 + -2z) = 2(z + -4) + 2(z + -3)

Reorder the terms:
14 + 4 + 7z + -2z = 2(z + -4) + 2(z + -3)

Combine like terms: 14 + 4 = 18
18 + 7z + -2z = 2(z + -4) + 2(z + -3)

Combine like terms: 7z + -2z = 5z
18 + 5z = 2(z + -4) + 2(z + -3)

Reorder the terms:
18 + 5z = 2(-4 + z) + 2(z + -3)
18 + 5z = (-4 * 2 + z * 2) + 2(z + -3)
18 + 5z = (-8 + 2z) + 2(z + -3)

Reorder the terms:
18 + 5z = -8 + 2z + 2(-3 + z)
18 + 5z = -8 + 2z + (-3 * 2 + z * 2)
18 + 5z = -8 + 2z + (-6 + 2z)

Reorder the terms:
18 + 5z = -8 + -6 + 2z + 2z

Combine like terms: -8 + -6 = -14
18 + 5z = -14 + 2z + 2z

Combine like terms: 2z + 2z = 4z
18 + 5z = -14 + 4z

Solving
18 + 5z = -14 + 4z

Solving for variable 'z'.

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

Add '-4z' to each side of the equation.
18 + 5z + -4z = -14 + 4z + -4z

Combine like terms: 5z + -4z = 1z
18 + 1z = -14 + 4z + -4z

Combine like terms: 4z + -4z = 0
18 + 1z = -14 + 0
18 + 1z = -14

Add '-18' to each side of the equation.
18 + -18 + 1z = -14 + -18

Combine like terms: 18 + -18 = 0
0 + 1z = -14 + -18
1z = -14 + -18

Combine like terms: -14 + -18 = -32
1z = -32

Divide each side by '1'.
z = -32

Simplifying
z = -32
