Eight added to twice a number is 42.
Give the number the name of ' X '.
8 + 2X = 42
' X ' is 17.
43
The number works out as 14
2n-4
The relevant expression (not equation) is:2*(n + 8) - 4 or2n + 8 - 4
The phrase "the sum of twice a number and 5 is 17" can be translated into an equation. Let the unknown number be represented by ( x ). The equation can be written as ( 2x + 5 = 17 ).

twice the difference of three times a number and eight
The relevant expression (not equation) is:2*(n + 8) - 4 or2n + 8 - 4
Twice a number minus two giving us the answer as eight is number 5.
2x/8; x = the number
"the sum of 2" and "twice" "a number" "is" "36"2+2x=36 â–
One number is eight more than twice another if their difference is 25. The larger number is 42
2n + 3
It is the equation W = 2n + 5.
