27 2+7 = 9 X 3 = 27
x + x + 1 + x + 2 = 3x + 3 = 3 times the middle number
The equation for three times the sum of a number ( x ) and five times the number can be expressed as ( 3(x + 5x) = 36 ). Simplifying this gives ( 3(6x) = 36 ), or ( 18x = 36 ). To solve for ( x ), divide both sides by 18, resulting in ( x = 2 ).

3x^2 + 6
3x+2
3x + (x-2) ----> 3x + x - 2 = 4x - 2, so the answer is four times the number, minus 2.
2x3=6+4=10 2.
If: 2+3x = 77 Then: x = 25

x + x + 1 + x + 2 = 3x + 3 = 3 times the middle number
The equation for three times the sum of a number ( x ) and five times the number can be expressed as ( 3(x + 5x) = 36 ). Simplifying this gives ( 3(6x) = 36 ), or ( 18x = 36 ). To solve for ( x ), divide both sides by 18, resulting in ( x = 2 ).
2*4 + 3*x = 34
There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.
