For this case we have the following inequality:
[tex]6.7\geq 0.2x + 4.5[/tex]
Subtracting 4.5 from both sides of the inequality:
[tex]6.7-4.5\geq -0.2x\\2.2\geq -0.2x[/tex]
Dividing between 0.2 on both sides:
[tex]\frac {2.2} {0.2} \geq-x\\11 \geq-x[/tex]
We multiply by -1 on both sides, taking into account that the sense of inequality changes:
[tex]-11 \leq x[/tex]
ANswer:
[tex]x \geq-11[/tex]
