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


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

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

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

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

Combine like terms: -3 + -15 = -18
-18 + 18z + -5z = 5(z + 1)

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