Four times of a number n is 23 more than twice the number

Answer 1

4n = 23+2n

divide both sides by 2

2n = 11.5 +n

subtract n from both sides

n = 11.5

Answer 2

Since n represents an unknown number, four times that number is represented by 4n. Twice the number is represented by 2n.

4n = 23 + 2n (4 times the number IS (=) 23 more than twice the number).

2n = 23

n = 23/2 (or 11.5)

4n = 46

2n = 23

23 more than 23 is indeed 46.
