Simplifying
2(5z + -1) + -5(z + 9) = 2(z + 1)

Reorder the terms:
2(-1 + 5z) + -5(z + 9) = 2(z + 1)
(-1 * 2 + 5z * 2) + -5(z + 9) = 2(z + 1)
(-2 + 10z) + -5(z + 9) = 2(z + 1)

Reorder the terms:
-2 + 10z + -5(9 + z) = 2(z + 1)
-2 + 10z + (9 * -5 + z * -5) = 2(z + 1)
-2 + 10z + (-45 + -5z) = 2(z + 1)
