Solution for 7z+2(z-12)=2(z-13)+3(2z+1) equation:


Simplifying
7z + 2(z + -12) = 2(z + -13) + 3(2z + 1)

Reorder the terms:
7z + 2(-12 + z) = 2(z + -13) + 3(2z + 1)
7z + (-12 * 2 + z * 2) = 2(z + -13) + 3(2z + 1)
7z + (-24 + 2z) = 2(z + -13) + 3(2z + 1)

Reorder the terms:
-24 + 7z + 2z = 2(z + -13) + 3(2z + 1)

Combine like terms: 7z + 2z = 9z
-24 + 9z = 2(z + -13) + 3(2z + 1)

Reorder the terms:
-24 + 9z = 2(-13 + z) + 3(2z + 1)
-24 + 9z = (-13 * 2 + z * 2) + 3(2z + 1)
-24 + 9z = (-26 + 2z) + 3(2z + 1)

Reorder the terms:
-24 + 9z = -26 + 2z + 3(1 + 2z)
-24 + 9z = -26 + 2z + (1 * 3 + 2z * 3)
-24 + 9z = -26 + 2z + (3 + 6z)

Reorder the terms:
-24 + 9z = -26 + 3 + 2z + 6z

Combine like terms: -26 + 3 = -23
-24 + 9z = -23 + 2z + 6z

Combine like terms: 2z + 6z = 8z
-24 + 9z = -23 + 8z

Solving
-24 + 9z = -23 + 8z

Solving for variable 'z'.
