twice the difference of three times a number and eight
2x - 7 = -1
The algebraic equation for the given statement can be expressed as: (2a + 3 > 49). This represents that when you take twice the unknown number (a) and add three, the result is greater than forty-nine.
2x + 8 = 50
The expression "eight more than twice a number" can be written as 2x + 8, where x represents the unknown number. This expression indicates that you should first multiply the number by 2 and then add 8 to the result. For example, if the number is 5, then 2(5) + 8 = 10 + 8 = 18.
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

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
