Solution for (2z-1)-2(2z+4)=2(z+1) equation:


Simplifying
(2z + -1) + -2(2z + 4) = 2(z + 1)

Reorder the terms:
(-1 + 2z) + -2(2z + 4) = 2(z + 1)

Remove parenthesis around (-1 + 2z)
-1 + 2z + -2(2z + 4) = 2(z + 1)

Reorder the terms:
-1 + 2z + -2(4 + 2z) = 2(z + 1)
-1 + 2z + (4 * -2 + 2z * -2) = 2(z + 1)
-1 + 2z + (-8 + -4z) = 2(z + 1)
