y = 12.

<em>Put the value of y to the equation 2x - y = 4:</em>

2x - 12 = 4 <em>add 12 to both sides</em>

2x = 16 <em>divide both sides by 2</em>

x = 8

<h3>Answer: x = 8 and y = 12</h3>

What is the value of x?

damaskus [11]

Answer:

x = 19.

Step-by-step explanation:

By the tangent - secant theorem:

BD^2 = AB * EB

so:

8^2 = (x - 7 + 4) * 4

4(x - 3) = 64

4x - 12 = 64

4x = 64 + 12 = 76

x = 76/4

= 19.
