Answer: x >= -6.2

Explanation:

Simplify this first by dividing each side by 5

5|x|+6>/5=1/5

|x| + 6 ≥ 0.2

Since this is an absolute value inequality, we need to setup two inequalities

x+6 >= 0.2

x+6 >= -0.2

Solve Equation 1 → x+6 >= 0.2

Subtract - 6 from both sides of the inequality

x+6 - 6>= 0.2 - 6

x ≥ - 5.8

Solution to absolute value equation 1 is

x >= -5.8

Solve Equation 2 → x+6 >= -0.2

Subtract - 6 from both sides of the inequality

x+6 - 6>= -0.2 - 6

x ≥ - 6.2
