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

27 2+7 = 9 X 3 = 27
x + x + 1 + x + 2 = 3x + 3 = 3 times the middle number
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.
2*4 + 3*x = 34
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 ).
