Given the following inequality:
[tex]10+b\le-1[/tex]You need to remember that the following symbol means "Less than or equal to":
[tex]\le[/tex]In order to find the solution of the given inequality, you need to apply the Subtraction property of inequality, which states that if:
[tex]aThen:[tex]a-cAnd if[tex]a>b[/tex]Then:
[tex]a-c>b-c[/tex]Therefore in this case, you must subtract 10 from both sides of the inequality. Then, you get:
[tex]\begin{gathered} 10+b-(10)\le-1-(10) \\ b\le-11 \end{gathered}[/tex]The solution is:
[tex]b\le-11[/tex]
