Question

Write the equation for eight more than four times a number is equal to -20

Answer 1

4x+8=-20

Explanation:

Let's say the unknown number is x:

4 times a number: 4x

8 more: + 8

equal to -20: = -20

Putting it all together: 4x + 8 = -20

Answer 2

Answer: 4s + 8 = -20

Explanation:

We need to write an equation for the following:

"Eight more than 4 times a number is equal to -20"

We can start by choosing a letter to represent the number; I'll choose s.

So now, we can write "4 times a number" as 4s.

Next, the problem says "eight more than 4 times a number" so we add 8 and get 4s + 8.

Since this equals -20, we get: 4s + 8 = -20.

SOLVING FOR 'S'

Now we can go ahead and solve the equation for s. First, we subtract 8 from both sides

4s = -20 - 8

4s = -28

Next, we divide both sides by 4:

s = -7
