#color(green)(z=-3)#

Explanation:

Given
#color(white)("XXX")5z+10=2z+1#

Subtract #2z# from both sides so there is no variable term on the right
#color(white)("XXX")3z+10=1#

Subtract #10# from both sides so there is no constant term on the left
#color(white)("XXX")3z=-9#

Divide both sides by #3# to leave a simple #z# term on the left
#color(white)("XXX")z=-3#
