Question 915700
# 1


{{{2x+5=-7}}} Start with the given equation.



{{{2x=-7-5}}} Subtract {{{5}}} from both sides.



{{{2x=-12}}} Combine like terms on the right side.



{{{x=(-12)/(2)}}} Divide both sides by {{{2}}} to isolate {{{x}}}.



{{{x=-6}}} Reduce.



So the solution is {{{x=-6}}}

# 2


{{{(1/6)n+2=9}}} Start with the given equation.



{{{6((1/cross(6))n+2)=6(9)}}} Multiply both sides by the LCD {{{6}}} to clear any fractions.



{{{n+12=54}}} Distribute and multiply.



{{{n=54-12}}} Subtract {{{12}}} from both sides.



{{{n=42}}} Combine like terms on the right side.



So the solution is {{{n=42}}}
