See the entire solution process below:

Solve each individual term for #0#:

Solution 1)

#x = 0#

Solution 2)

#x - 7 = 0#

#x - 7 + color(red)(7) = 0 + color(red)(7)#

#x - 0 = 7#

#x = 7#

Solution 3)

#x + 3 = 0#

#x + 3 - color(red)(3) = 0 - color(red)(3)#

#x - 0 = -3#

#x = -3#

The solution is: #x = 0# and #x = 7# and #x = -3#
