Question

What is the equation if the problem is “twice a number plus 4 is 8”

Answer 1

in this case, number is x

twice a number means 2 of a number, so 2x

2x + 4 = 8 is the answer

Answer 2

Answer: 2n + 4 = 8

Explanation:

First, let the number be n.

Twice the number n is 2n. If we add 4, we get 2n + 4. This equals 8, so, we have: 2n + 4 = 8

Therefore, the equation is 2n + 4 = 8.

(optional) solve for n:

2n = 8 - 4

2n = 4

n = 2
