#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#
