Solve using method of intervals. please show step/explain. thank you

Answer 1

x ≤ 3

Explanation:

`(x-3)/(x+4)` ≤ 0

Multiply both sides by (x+4) so that both sides do not have any fractions.

x - 3 ≤ 0 × (x+4)

Remember that anything multiplied by 0 becomes 0.

x - 3 ≤ 0

Add both sides by 3 so that there is only x on the left side. (x - 3 + 3 = x)

x ≤ 0 + 3

x ≤ 3
