one number is 5 less than twice another if the sum of the number is 19 what are the numbers ?

Sagot :

Let x be the second number. 5 less than twice this is the first number, 2x-5

Their sum is 19:

x + 2x-5 = 19

Solving for x,

3x - 5 = 19

3x = 19 + 5

3x = 24

x = 8

Therefore, the two numbers are 11 and 8.
Representation: x - be the number ; y - be the other number
x = 2y - 5
x + y = 19
( 2y - 5 ) + y = 19
3y - 5 = 19
3y = 24
y = 8 ; x = 11
 Therefore, the two numbers are 8 and 11.
