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
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 ).
To solve the equation "Eight less than twice a number is fourteen," we can express it mathematically as ( 2x - 8 = 14 ), where ( x ) is the number. Adding 8 to both sides gives ( 2x = 22 ). Dividing both sides by 2 results in ( x = 11 ). Therefore, the number is 11.
Let the number be represented by ( x ). According to the problem, if the sum of the number and five is tripled, it can be expressed as ( 3(x + 5) ). This is equal to eight less than twice the number, or ( 2x - 8 ). Setting up the equation, we have ( 3(x + 5) = 2x - 8 ). Solving this gives ( x = -1 ).
Twice a number minus two giving us the answer as eight is number 5.
2x/8; x = the number
One number is eight more than twice another if their difference is 25. The larger number is 42
