The sum of two numbers is 14 one number is two less than three times the other. find the numbers​
BigorU [14]

Answer:

The numbers are 10  and  4

Step-by-step explanation:

Let

x-----> one number

y----> the other number

we know that

x+y=14 ------> equation A

x=3y-2 -----> equation B

Substitute equation B in equation A and solve for y

3y-2+y=14

4y=14+2

y=16/4=4

Find the value of x

x=3(4)-2=10
