what to solve where is the full quea!??
Answer:
x = 12 , y = 10
Step-by-step explanation:
Let x , y are two numbers.
x > y
1 ) Three times the greater is 18 times their
difference
3x = 18( x - y )
x = 6( x - y )
x = 6x - 6y
6y = 5x
y = 5x/6 ——-( 1 )
2 ) 4 times the smaller is 4 less than twice
the sum of the two
4y + 4 = 2 ( x + y )
2y + 2 = x + y
y = x -2 ——( 2 )
From ( 1 ) and ( 2 ) ,
5x/6 = x -2
( 5x /6 ) - x = -2
( 5x - 6x ) /6 = -2
-x = -12
x = 12
Put x = 12 in equation ( 2 ) , we get
y = 12 - 2
y = 10
Therefore ,
x = 12 , y = 10

Answer:
Step-by-step explanation:
Apply the intersecting chord theorem.
DK × BK = AK × CK
12(4x+1) = 14(3 + 3x)
Expand brackets.
48x + 12 = 42 + 42x
Subtract 42x and 12 from both sides.
6x = 30
Divide both sides by 6.
x = 5
