Question

solve 6(5-2z)+5z=8z-3(16-3z)
please show work

Answer 1

\[30-12z+5z=8z-48+9z\]
\[30-7z=17z-48\]
\[78=24z\]
\[78/24=24z/24\]
\[z=3.25\]

Answer 2

multiply and you get 30-12z +5z=8z-48+9z
move all the numbers with z to one side and numbers without z to the other
30+48=12z-5z+8z+9z remember the signs change when you move them from one side to another

then combine! 78= 24z
divide both sides by 24
z=3.25
