whats the solution to (x+4)/3<=5?

(x+4)/3<=5
*3
x+4 <= 15
-4
x<=11

(x + 4)/3 <= 5
x + 4 <= 15
x <= 11

Answer: x <= 11

Proof:
(11 + 4)/3 <= 5
15/3 < = 5
5 <= 5

(x+4)/3<=5
x+4<=5.3
x+4<=15
x<=15-4
x<=11

(x+4)/3 <= 5
x + 4 <= 15
x <= 11

x is less than or equal to eleven.

( x + 4 ) / 3 ≤ 5

x + 4 ≤ 15

x ≤ 11

(x + 4)/3 ≤ 5
x + 4 ≤ 3(5)
x + 4 ≤ 15
x ≤ 15 - 4
x ≤ 11

wrong

x + 4 = 3 X 5
x + 4 = 15
x = 15- 4
x = 11

(x+4)/3=5

(x+4)=5*3

x+4=15

x=15-4

x=11
