#q = 55#

Explanation:

#8 = q/5 +(-3)#

To solve this, we need to isolate the pronumeral, in this case, it is #q#.

#8 = q/5 -3#

#8 color(red)(+3)= q/5 color(red)(cancel(color(black)(-3) -3))#

#11 color(red)(xx5) = q/color(red)(cancel(color(black)(5))) xx color(red)(cancel(5))#

#color(blue)(q = 55)#

To prove this, we can substitute the pronumeral for the given value.

#8 = 55/5 +(-3)#

#8 = 55/5 -3#

#8 = 11 -3#
