Solve a linear inequalities and express the interval notation?

Question

3x+4≥5x-8

Answer 1

3x+4≥5x-8

-2x ≥ -12

x ≥ 6

Answer 2

3x + 4 ≥ 5x - 8 (subtract 5x from both sides)

-2x + 4 ≥ -8 (subtract 4 from both sides)

-2x ≥ -12 (divide both sides by -2 and flip the inequality sign)

x ≤ 6

(-inf, 6] <===ANSWER

Remember that you always flip the inequality sign whenever you multiply or divide both sides of the inequality by a negative value.

Answer 3

haha i remember this

x is greater than or equal to 6

im not sure what the interval notion means though
