Solution for 6(3z-1)-5(z+3)=8(z+1) equation:


Simplifying
6(3z + -1) + -5(z + 3) = 8(z + 1)

Reorder the terms:
6(-1 + 3z) + -5(z + 3) = 8(z + 1)
(-1 * 6 + 3z * 6) + -5(z + 3) = 8(z + 1)
(-6 + 18z) + -5(z + 3) = 8(z + 1)

Reorder the terms:
-6 + 18z + -5(3 + z) = 8(z + 1)
-6 + 18z + (3 * -5 + z * -5) = 8(z + 1)
-6 + 18z + (-15 + -5z) = 8(z + 1)

Reorder the terms:
-6 + -15 + 18z + -5z = 8(z + 1)

Combine like terms: -6 + -15 = -21
-21 + 18z + -5z = 8(z + 1)

Combine like terms: 18z + -5z = 13z
-21 + 13z = 8(z + 1)

Reorder the terms:
-21 + 13z = 8(1 + z)
-21 + 13z = (1 * 8 + z * 8)
-21 + 13z = (8 + 8z)

Solving
-21 + 13z = 8 + 8z

Solving for variable 'z'.
