Question

Find two numbers whose sum equals 299 , and in which one numbe is one less than 3 times the value of the other number .

Answer 1

Answer:

$x=75 \ \ and \ \ y=224$

Step-by-step explanation:

suppose the numbers are x and y. Then

$x+y=299$ -------------(1)

One number say y is one less than 3 times the value of the other number say x

$y=3x-1$ -------------(2)

Substitute y=3x-1 in equation (1)

$x+3x-1=299$

$4x=300\\ x=75$

Now put x=75 in equation (2)

$y= 3(75)-1\\y= 224$
