Solution for 2z-(z-1)-6(1-z)=3(3z+20)+11z equation:


Simplifying
2z + -1(z + -1) + -6(1 + -1z) = 3(3z + 20) + 11z

Reorder the terms:
2z + -1(-1 + z) + -6(1 + -1z) = 3(3z + 20) + 11z
2z + (-1 * -1 + z * -1) + -6(1 + -1z) = 3(3z + 20) + 11z
2z + (1 + -1z) + -6(1 + -1z) = 3(3z + 20) + 11z
2z + 1 + -1z + (1 * -6 + -1z * -6) = 3(3z + 20) + 11z
2z + 1 + -1z + (-6 + 6z) = 3(3z + 20) + 11z

Reorder the terms:
1 + -6 + 2z + -1z + 6z = 3(3z + 20) + 11z

Combine like terms: 1 + -6 = -5
-5 + 2z + -1z + 6z = 3(3z + 20) + 11z

Combine like terms: 2z + -1z = 1z
-5 + 1z + 6z = 3(3z + 20) + 11z

Combine like terms: 1z + 6z = 7z
-5 + 7z = 3(3z + 20) + 11z

Reorder the terms:
-5 + 7z = 3(20 + 3z) + 11z
-5 + 7z = (20 * 3 + 3z * 3) + 11z
-5 + 7z = (60 + 9z) + 11z

Combine like terms: 9z + 11z = 20z
-5 + 7z = 60 + 20z

Solving
-5 + 7z = 60 + 20z

Solving for variable 'z'.

-5 + -13z = 60 + 20z + -20z

Combine like terms: 20z + -20z = 0
-5 + -13z = 60 + 0
-5 + -13z = 60

Add '5' to each side of the equation.
-5 + 5 + -13z = 60 + 5

Combine like terms: -5 + 5 = 0
0 + -13z = 60 + 5
-13z = 60 + 5

Combine like terms: 60 + 5 = 65
-13z = 65
