2(x+7)3X



I think... look it up  though to be sure

Answer 2

Part 1: Write your equation
The question is asking for you to put "twice the sum of a number and seven is three times the number" into math. 

1) "is" means equal to, calling for the "=" sign
2) "a number" is what you're trying to find, aka the variable. Let's call this variable "n."

1) On the left of "is"/the equal sign, you have "twice the sum of a number and seven." That means two times (aka twice) the sum of the variable n (aka the number) and seven. In math, that would be:
2*(n + 7)

2) On the right of "is"/the equal sign, you have "three times the number." That means three times the variable n (aka the number). In math that would be:
3*n

3) Put that all together to get your final equation:
2(n + 7) = 3n


Part 2: Solve the equation for your number, aka "n"
1) Distribute the 2 to the n and the 7 using the distributive property
2(n + 7) = 3n
2*n + 2*7 = 3n
2n + 14 = 3n

2) Move everything with n to one side of the equal sign by subtracting 2n from both sides:
2n + 14 = 3n
14 = n

The missing number is 14.
