How do you solve and check your solutions to #-3.3a=19.8#?

Answer 1

#-6#

The equation is #-3.3a = 19.8#.

First, we multiply both sides by 10. #-3.3acolor(blue)*color(blue)10=19.8color(blue)*color(blue)10# Which is equal to #-33a=198#. Divide both sides by #-33# #(-33a)/33 = 198/-33#

Simplify: #a=-6#. ( #199-:-33=-6)#
