Answer 1

Answer:

$x = 18$

Step-by-step explanation:

Vertically Opposite Angles are equal..

so,

$x + 54 = 4x \\ 54 = 4x - x \\ 54 = 3x \\ \frac{54}{3} = \frac{3x}{3} \\ 18 = x$

Answer 2

Answer:

$x + 54 \: and \: 4x \: are \: opposite \: so \\ x + 54 = 4x \\ x \: terms \: togather \\ 4x - x = 54 \\ 3x = 54 \\ x = \frac{54}{3} \\x = 18 \\ thank \: you$
