What does n mean in 2n plus 1 equals 22?
2n + 1 = 22 Take 1 from the left side of the equal side and move it to the right side. To do this subtract 1 from the left side and on the right side 2n + 1 - 1 = 22 -1 2n = 21 Then divide both sides by 2 in order to isolate n. 2n / 2 = 21 /2 n = 21/2 or 10.5 Tada! The answer is 21/2 or 10.5.
