$x>= - 5.9$

$x- 2.2\geq - 8.1$

Solution

Add $color(red)(2.2)$ to both sides

$x - 2.2 + color(red)(2.2) >= -8.1 + color(red)(2.2)$

$x + 0 >= -8.1 + 2.2$

$x >= -8.1 + 2.2$

$x>= - 5.9$

See a solution process below:

Add $color(red)(2.2)$ to both sides of the inequality to solve for $x$ while keeping the inequality balanced:

$x - 2.2 + color(red)(2.2) >= -8.1 + color(red)(2.2)$

$x - 0 >= -5.9$

$x >= -5.9$
