One number is four more than a second number. Two times the first number is 8 more than four times the second number.

The required numbers are:

First number = 4

Second number = 0

Step-by-step 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

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
