See a solution process below:

Solving for #w#:

#2w + 9m = 77#

#2w + 9m - color(red)(9m) = 77 - color(red)(9m)#

#2w + 0 = 77 - 9m#

#2w = 77 - 9m#

#(2w)/color(red)(2) = (77 - 9m)/color(red)(2)#

#(color(red)(cancel(color(black)(2)))w)/cancel(color(red)(2)) = (77 - 9m)/2#

#w = (77 - 9m)/2#

Solving for #m#:

#2w + 9m = 77#

#2w - color(red)(2w) + 9m = 77 - color(red)(2w)#

#0 + 9m = 77 - 2w#

#9m = 77 - 2w#

#(9m)/color(red)(9) = (77 - 2w)/color(red)(9)#

#(color(red)(cancel(color(black)(9)))m)/cancel(color(red)(9)) = (77 - 2w)/9#

#m = (77 - 2w)/9#
