Solution for 2(5z-1)-2(z+8)=5(z+1) equation:


Simplifying
2(5z + -1) + -2(z + 8) = 5(z + 1)

Reorder the terms:
2(-1 + 5z) + -2(z + 8) = 5(z + 1)
(-1 * 2 + 5z * 2) + -2(z + 8) = 5(z + 1)
(-2 + 10z) + -2(z + 8) = 5(z + 1)

Reorder the terms:
-2 + 10z + -2(8 + z) = 5(z + 1)
-2 + 10z + (8 * -2 + z * -2) = 5(z + 1)
-2 + 10z + (-16 + -2z) = 5(z + 1)

Reorder the terms:
-2 + -16 + 10z + -2z = 5(z + 1)

Combine like terms: -2 + -16 = -18
-18 + 10z + -2z = 5(z + 1)

Combine like terms: 10z + -2z = 8z
-18 + 8z = 5(z + 1)

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

Solving
-18 + 8z = 5 + 5z

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.
