Which of following not a way to represent the solution of inequality 5(x + 2) greater than or equal to 7x + 2(x − 1)?
(a )a number line with a closed circle on 3 and shading to the right
(b) a number line with a closed circle on 3 and shading to the left
(c) 3 greater than or equal to x
(d) x less than or equal to 3

A number line with a closed circle on 3 and shading to the left

Step-by-step explanation:

Equation :

Divide by 4 both sides

So,

So, Therefore, the solution set is:
