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.

Answer:
y=3 x=-20
Step-by-step explanation:
2(3y-5)+12y=-4
6y-10+12y
18y-10=-4
18y=6
y=3
2x+12(3)=-4
2x+36=-4
2x=-40
x=-20
