Isolate variable term: Isolate the variable term in −2t−1≤−9. Add 1 to both sides of the inequality to move the constant term to the right side. −2t−1+1≤−9+1−2t≤−8
Add 1 to both sides: Now, divide both sides of the inequality by −2 to solve for t.Remember that when you divide or multiply both sides of an inequality by a negative number, you must reverse the inequality sign.−2t/−2≥−8/−2t≥4
