8a-4(-5a-2)=12a
Do the multiplication first
8a+20a+8=12a
Transpose term with variable to the left and with no variable to the right,Add, combine like terms.
28a-12a = -8
16a = -8
Divide left and right terms by 16, you get:
a = -8/16
Reduuce to lowest term
a = -1/2

8a-4(-5a-2)=12a
8a +20a+8=12a distribute the -4 to the # in the parentheses
28a+8=12a Add like terms
-28a+28a+8=12a-28a Subtract 28a from both sides
8=-16a
8/-16=-16a/16 Divide by -16 to get a by itself
-1/2=a
