Answer:

Step-by-step explanation:

answer:

3x - 18 = 2y

5x - 6y = 14

5x - 3*(2y) = 14

5x - 3*(3x - 18) = 14

5x - 9x + 54 = 14

-4x = -40

x = 10

3*10 - 18 = 2y

30 - 18 = 2y

12 = 2y

y = 6

Tell whether the angles are adjacent or vertical. Then find the value of x.

lozanna [386]

Answer:

$x = 25$

Step-by-step explanation:

The angles are vertical since they form from two lines crossing at a point and they share a same vertex.

Vertical angles are equal so

$4x - 25 = 75$

$4x = 100$

$x = 25$
