hartnn · Answer

Since vertical angles are congruent, you can equate them, so u get 
3x+20 = 5x-16
did u get the a) part ?

anonymous · Answer

kind of is that how i fill out the a part?

hartnn · Answer

yes.
now for b) part
u subtract 5x from both sides, u get 
-2x+20 = -16

anonymous · Answer

okay ;D

hartnn · Answer

now subtracting 20 from both sides, we get 
-2x=-16-20
-2x=-36

anonymous · Answer

so that is b?

hartnn · Answer

that was c) part -2x=-36
now d) part 
dividing -2 on both sides 
x= -36/-2 = 18
x=18
