2x + 3 = 15- 3 from both sides2x = 12divide both sides by 2x = 6
If the question contains a typing error and should read, "The reciprocal of a number plus the reciprocal of twice the number equals one half ?" Then let 'n' be the number.1/n + 1/2n = 1/2 : Multiply by 2n2 + 1 = n : n = 3NOTE : 1/3 + 1/6 = 1/2The answer is 3.
The difference between 53 and 5 - 3 can be calculated as follows: 53 is simply the number fifty-three, while 5 - 3 equals 2. Therefore, the difference between these two values is 53 - 2, which equals 51. In summary, 53 is a larger number, and the operation 5 - 3 results in a smaller value.
Let the number be represented by ( x ). According to the problem, twice the number minus 3 equals 25, which can be written as the equation ( 2x - 3 = 25 ). Adding 3 to both sides gives ( 2x = 28 ), and dividing both sides by 2 results in ( x = 14 ). Therefore, the number is 14.
3*(n - 5) = 2*n + 11
20
It is 3*n - 5
36 is twice the product of its digits multiplied. 3 times 6 equals 18, and 18 times 2 equals 36.
twice an unknown number less one and one-half times the same number equals two ---- Let the unknown number be "x":: Equation: 2x - (3/2)x = 2
2x + 3 = 15- 3 from both sides2x = 12divide both sides by 2x = 6

twice a number n is 2n plus 3 is + 3 → twice a number n plus 3 is 2n + 3.

The second would suggest that x equals the string "=3".
