Let x = the number you are looking for.
So, 3x + 7 = 52, which is easily solvable for x as follows:
3x + 7 = 52
3x = 45
x = 15

Let
3x + 7 = 7 more than three times a number
52 = Total.
- - - - - - - - - - - - - - - - - - - - - - - - -
3x + 7 = 52
3x + 7 - 7 = 52 - 7
3x = 45
3x/3 = 45/3
x = 15
The answer is x = 15
Insert the x value into the equation
- - - - - - - - - - - - - - - - - - - - - - -
Check
3x + 7 = 52
3(15) + 7 = 52
45 + 7 = 52
52 = 52

in other words...it's saying
3x+7=52
so you subtract 7 from both sides...
3x=45
divide both sides by 3
x=15
