The larger of two numbers is four times the smaller number, and their difference is 18. Find the two numbers.
podryga [215]

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:

  • 5/7 - (3/14 + 3/14) = 2/7

See the steps of solution:

  • 5/7 - (3 + 3)/14 =                Add fractions with same denominator
  • 5/7 - 6/14 =                        Simplify
  • 5/7 - 3/7 =                         Subtract fractions with same denominator
  • (5 - 3)/7 =                           Simplify
  • 2/7                                     Answer
