Help me on this question

Answer 1

`x + 54 \: and \: 4x \: are \: opposite \: so \\ x + 54 = 4x \\ x \: terms \: togather \\ 4x - x = 54 \\ 3x = 54 \\ x = (54)/(3) \\x = 18 \\ thank \: you`

Answer 2

`x = 18`

Explanation:

Vertically Opposite Angles are equal..

so,

`x + 54 = 4x \\ 54 = 4x - x \\ 54 = 3x \\ (54)/(3) = (3x)/(3) \\ 18 = x`
