Primeiro multiplica o -2 com tudo que tem dentro do parenteses (chuveirinho) -114 = -5x -2(4x+18)
-2 . 4x = -8x + -2 . 18 = -36 = -8x-36
Agora soma os números com incógnitas (no caso x)
-114 = - 5x - 8x -36
Joga a incógnita do outro, tornando positiva
-114 = -13x - 36
13x -114 = -36
e o 114 do outro lado, ficando positiva também
13x -114 = -36
13x = - 36 + 114
13x = 78
x = 78 /13
x= 6

Answer:
B and C describe vertical angles
Step-by-step explanation:
Point R will be the common vertex of any possible pair of vertical angles.
For a given line segment, such as AE, one end will designate a side of one of the vertical angles, and the other end will designate a side of the other angle of the pair.
For example, Choice B uses the crossing segments TN and FL and identifies the vertical angles TRF and NRL.
Choice C uses segments FL and AE to identify the vertical angles LRE and FRA.
__
Choice A does not involve crossing segments. Choice D makes use of segment AE, but the other points S and N are not on the same segment.
