Question 295701
{{{9x+40<=15-x}}} Start with the given inequality.



{{{9x<=15-x-40}}} Subtract {{{40}}} from both sides.



{{{9x+x<=15-40}}} Add {{{x}}} to both sides.



{{{10x<=15-40}}} Combine like terms on the left side.



{{{10x<=-25}}} Combine like terms on the right side.



{{{x<=(-25)/(10)}}} Divide both sides by {{{10}}} to isolate {{{x}}}. 



{{{x<=-5/2}}} Reduce.

Answer:


So the solution is {{{x<=-5/2}}}
