Twice a number can be written as 2n.

Four times the number can be written as 4n.

If the sum of 2n and 4n equals 54, then:

6n = 54

Divide both sides by 6 to solve for n:

n = 9

22+(30-4) ÷2 And 18+(22-4) ÷6
schepotkina [342]

22 + (30 - 4) divided by 2

30 - 4 = 26

26/2 = 13

22 + 13 = 35

35

18 + (22 - 4) divided by 6

22 - 4 = 18

18 divided by 6 = 3

18 + 3 = 21

21
