To write this algebraically:
2x+18>25
and solve:
2x>25-18
x>7/2
Therefore x (a number) must be greater than 7/2.
x = 11

Consider 4 cases 1. The sum of any two positive numbers is clearly greater than either number. 2. The sum of any two negative numbers is LESS than either of the two numbers. ( (Look at -2+(-3)=-5 .) 3. The sum of any negative number and a positive number is always greater than the negative number but less than the positive number. (Look at -2+3=1, or -5+3=-2) 4. The sum of any number and 0 is that number so it is not greater. So it appears that the sum of any two numbers is greater than either of the two numbers when the two number are both positive.
The sum of a positive number and a negative number is positive when the magnitude of the positive number is greater than the magnitude of the negative number. In other words, if the positive number is larger than the absolute value of the negative number, their sum will be positive. For example, if we have 5 (positive) and -3 (negative), their sum is 2, which is positive. Conversely, if the negative number's magnitude is greater, the sum will be negative.
Given an arbitrary odd natural number greater than five, x, let y = x - 3, then y is an even number greater than 2. By assumption we have that y is the sum of two primes, say y1 and y2, but then x = y1 + y2 + 3 (which is the sum of three primes).
2a+3>49
2n + 3 > 49 n > 23
Let the number be x and so: 2x+3 > 49
9218 9425
Not always, if the smaller number is 0 or a negative number. Then their sum will be equal or less than the greater number.

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.

8 greater than the original number.
Correction: Here is the equation you will need to solve: 7N - 30 = 2N + 5 --> 5N = 35 --> N = 7
