The relevant expression (not equation) is:
2*(n + 8) - 4 or
2n + 8 - 4
The equation can be written as 2x * 8 - 4, where x is the number.
12x
Eight added to twice a number is 42.Give the number the name of ' X '.8 + 2X = 42' X ' is 17.
2x/8; x = the number

2x + 8
twice the difference of three times a number and eight
yes and yes
12x
Twice that number!
Twice a number minus two giving us the answer as eight is number 5.
Eight added to twice a number is 42.Give the number the name of ' X '.8 + 2X = 42' X ' is 17.
2x/8; x = the number

One number is eight more than twice another if their difference is 25. The larger number is 42
2x + 8
The number is ' pi ' = 3.1416 (rounded)
If the number is x then the expression is: 2x+8
