Question

Express the Set -3x+25>2x+5 using interval notation

Answer 1

-3x - 2x > 5 - 25
-5x > -20
x < 4

in interval notation this is (-∞, 4)

Answer 2

(4,-∞) since you have to isolate the x first which would give you this inequality: x<4. This means that any number less than 4 can be the solution.
