Q. Solve for

x

, your answer must be simplified.

-4+x\leq9

Isolate $x$ by adding $4$ : Step $1$ : Isolate $x$ by adding $4$ to both sides of the inequality. $\newline$ $-4 + x + 4 \leq 9 + 4$ $\newline$ $x \leq 13$
Check solution with $x = 13$ : Step $2$ : Check if the solution makes sense by substituting a value less than or equal to $13$ for $x$ . $\newline$ Let $x = 13$ : $-4 + 13 = 9$ , which satisfies $-4 + x \leq 9$ .
