Let X equal the mystery number in this example. In this case, a number plus 3 times that number would be expressed as X+3X, and 76 would simply be expressed as 76. Now, to the equation:
X+3X= 76 First, simplify the left side of the equation
4X= 76 Next, divide both sides by 4 to get X by itself, and hence your answer
X=19
the answer is 9

the number is 11
-24
3(x+5)
The sum of the two prime numbers 3 and 73 is 76.
5x + 6
the answer is 9
