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 answser is x = 15
Insert the x value into the equation
- - - - - - - - - - - - - - - - - - - - - - - -
Check
3x + 7 = 52
3(15) + 7 = 52
45 + 7 = 52
52 = 52

the answer is 15
3 times a number, then add 7 = 52
(3 x n) + 7 =52
(3 x n) =52-7
3 x n =45
n=45/3
n=15

3 x 15 is 45 + 7 is 52
1st of all subtract 7 from 52 to give you 45. Divide 45 by 3 to give you 15. Not too hard at all.

Think about it this way -- 52 minus seven, divided by three, is your number. 52 - 7 = 45, and 45 / 3 = 15. So 15 is the answer.

7+3x=52. Solve for x.

3x + 7 = 52 (Subtract 7 from both sides)
3x = 45 (Divide both sides by 3)
x = 15
Check:
3(15) + 7 = 52
45 + 7 = 52
52 = 52
