Question 223017


{{{-1=5-z-z}}} Start with the given equation.



{{{-1=-2z+5}}} Combine like terms on the right side.



{{{-1-5=-2z}}} Subtract {{{5}}} from both sides.



{{{-6=-2z}}} Combine like terms.



{{{-2z=-6}}} Rearrange the equation.



{{{z=(-6)/(-2)}}} Divide both sides by {{{-2}}} to isolate {{{z}}}.



{{{z=3}}} Reduce.
