Solution for -[7z-(10z+7)]=7+(2z+0) equation:


Simplifying
-1[7z + -1(10z + 7)] = 7 + (2z + 0)

Reorder the terms:
-1[7z + -1(7 + 10z)] = 7 + (2z + 0)
-1[7z + (7 * -1 + 10z * -1)] = 7 + (2z + 0)
-1[7z + (-7 + -10z)] = 7 + (2z + 0)

Reorder the terms:
-1[-7 + 7z + -10z] = 7 + (2z + 0)

Combine like terms: 7z + -10z = -3z
-1[-7 + -3z] = 7 + (2z + 0)
[-7 * -1 + -3z * -1] = 7 + (2z + 0)
[7 + 3z] = 7 + (2z + 0)

Reorder the terms:
7 + 3z = 7 + (0 + 2z)
Remove the zero:
7 + 3z = 7 + (2z)
7 + 3z = 7 + (2z)

Add '-7' to each side of the equation.
7 + -7 + 3z = 7 + -7 + (2z)

Combine like terms: 7 + -7 = 0
0 + 3z = 7 + -7 + (2z)
3z = 7 + -7 + (2z)

Combine like terms: 7 + -7 = 0
3z = 0 + (2z)
3z = (2z)

Solving
3z = (2z)

Solving for variable 'z'.

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

Add '(-2z)' to each side of the equation.
3z + (-2z) = (2z) + (-2z)

Combine like terms: 3z + (-2z) = 1z
1z = (2z) + (-2z)

Combine like terms: (2z) + (-2z) = 0
1z = 0

Divide each side by '1'.
z = 0

Simplifying
z = 0
