In order to isolate y, we can multiply both sides by -5. Since we're multiplying by a negative we need to .
-5y≥5 y≤-25
The solution to the inequality is y-values less than or equal to -25.
Let's start by multiplying both sides by 7. Then, we can collect all x-terms on one side.
-3x≤720−x -21x≤20−x -20x≤20
The solution to the inequality is all x-values greater than or equal to -1.
Here we can subtract 3x and 8 from both sides to simplify the inequality. Further, we'll divide both sides by -10 and remember to flip the inequality sign.
-7x+8>3x+16 -10x+8>16 -10x>8 x<-108 x<-0.8
x<-0.8 is the solution set of the inequality.
