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


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

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

Reorder the terms:
-5 + 15z + -5(6 + z) = 8(z + 1)
-5 + 15z + (6 * -5 + z * -5) = 8(z + 1)
-5 + 15z + (-30 + -5z) = 8(z + 1)
