Answer:
see the explanation
Step-by-step explanation:
we have
[tex]15\geq 22+x[/tex]
Solve for x
subtract 22 both sides
[tex]15-22\geq x[/tex]
[tex]-7\geq x[/tex]
Rewrite the inequality
[tex]x \leq -7[/tex]
The solution is the interval (-∞,-7]
All real numbers less than or equal to -7
In a number line the solution is the shaded area at left of x=-7 (closed circle)
The arrow points left
The number x=-7 is included in the solution
