Question 763992
{{{-0.71-0.22n=1.29+0.78n}}} Start with the given equation.



{{{100(-0.71-0.22n)=100(1.29+0.78n)}}} Multiply both sides by 100 to clear out the decimals.



{{{-71-22n=129+78n}}} Distribute and multiply.



{{{-22n=129+78n+71}}} Add {{{71}}} to both sides.



{{{-22n-78n=129+71}}} Subtract {{{78n}}} from both sides.



{{{-100n=129+71}}} Combine like terms on the left side.



{{{-100n=200}}} Combine like terms on the right side.



{{{n=(200)/(-100)}}} Divide both sides by {{{-100}}} to isolate {{{n}}}.



{{{n=-2}}} Reduce.

Answer:


So the solution is {{{n=-2}}}
