Question 549296
{{{-6(5-2z)+5z = 8z-3(16-3z)}}}
{{{-30+12z+5z = 8z-48+9z}}} distributed the -6 and -3
{{{-30+17z=17z-48}}} added like terms
{{{-30=-48}}} subtracted 17z from both sides
z was canceled so this problem is invalid
{{{-6(5-2z)+5z}}} does not equal {{{8z-3(16-3z)}}}



thanks for catching my mistake.
