The numbers are 4and 10.

Step by step solution

01

Step 1. Given information

We have been given that the sum of two numbers is 14. One number is two less than three times the other.

We have to find the numbers.

02

Step 2. Form the equations

From the statement: The sum of two numbers is 14. One number is two less than three times the other.

We get,

x+y=14_____(1)x=3y-2______(2)

03

Step 3. Solve for the equations

Put equation (2) in (1),

x+y=143y-2+y=144y-2=144y=16y=4

Put the value of y in (2)

x=3y-2x=3(4)-2x=12-2x=10
