See a solution process below:

Solve each of the terms on the left for #0#:

Solution 1

#x - 4/5 = 0#

#x - 4/5 + color(red)(4/5) = 0 + color(red)(4/5)#

#x - 0 = 4/5#

#x = 4/5#

Solution 2

#x + 8/9 = 0#

#x + 8/9 - color(red)(8/9) = 0 - color(red)(8/9)#

#x + 0 = -8/9#

#x = -8/9#

The Solutions Are: #x = 4/5# and #x = -8/9#
