#a = 1#

Explanation:

#7(8a-7) = 11-4a#

#56a - 49 color(red)(+4a)= 11 color(red)(cancel(color(black)(-4a) +4a))#

#56a + 4a color(red)(cancel(color(black)(- 49) + 49))= 11 color(red)(+ 49)#

#(color(red)(cancel(color(black)(60)))a)/color(red)(cancel(60)) = 60/color(red)(60)#

#color(blue)(a = 1)#
