the inequality is:


4x+5\le13

Now we can rest 5 in bout sides so:


\begin{gathered} 4x\le13-5 \\ 4x\le8 \end{gathered}

Now we divide by 4 so:


\begin{gathered} x\le(8)/(4) \\ x\le2 \end{gathered}

English solution: all real numbers that are less or equal to 2

Algebraic solution:


x\le2

Number line solution:

Interval notation:


(-\infty,2\rbrack

Builder notation:


\mleft\lbrace x\parallel x\le2\mright\rbrace
