Question 725263
{{{16(z+3)=4(z+9)}}} Start with the given equation.



{{{16z+48=4z+36}}} Distribute.



{{{16z=4z+36-48}}} Subtract {{{48}}} from both sides.



{{{16z-4z=36-48}}} Subtract {{{4z}}} from both sides.



{{{12z=36-48}}} Combine like terms on the left side.



{{{12z=-12}}} Combine like terms on the right side.



{{{z=(-12)/(12)}}} Divide both sides by {{{12}}} to isolate {{{z}}}.



{{{z=-1}}} Reduce.

Answer:


So the solution is {{{z=-1}}}
