One number is eight less than a second number. Four times the first is 6 more than 2 times the second. Find the numbers.

The value of the first number is

Answer 1

Step-by-step explanation: The required numbers are:

First number = 4

Second number = 0

Explanation:

Let First number = x

second number = y

We are given:

One number is four more than a second number.

Writing in mathematical form:

Two times the first number is 8 more than four times the second

Writing in mathematical form:

Now, we will solve these equations by substitution to find values of x and y

Let:

Now, putting value of x from eq(1) into eq(2)

So, we get y=0

Now put value of y in equation 1 to get value of x

So, we get x=4

So, the required numbers are:

First number = 4

Second number = 0
