Solve the inequality $2x - 5 \le -x +12$. Give your answer as an interval.
Thank you in advance.
similar to simplifying equations, we can add and subtract things to both sides in inequalities.
so for this inequality, let's start by adding x to both sides.
\(2x + x - 5 \le 12\)
now let's add five to both sides.
\(3x \le 12 + 5\)
\(3x \le 17\)
let's divide both sides by 3.
\(x \le \frac{17}{3}\)
so, in interval notation, the answer would be:
\((-∞, \frac{17}{3}]\)
hope this helped! please let me know if you are confused about anything i did :)
