Solve the inequality. (Enter INFINITY for infinity and -INFINITY for -infinity as needed.)
6<=5 - y
6 <= 5 - y
6 - 5 <= - y
1 <= - y Multiply both sides by -1
______________________________________
Remark :
If you multiply or divide both sides of an inequality by a negative number, you must reverse the direction of the inequality sign.
