Answer:
but I think this is the intended interpretation.
Let x be the number.
Then the sum of the number and 3 multiplied by 5 is: 5(x + 3). (Last time, I would have listed this as x + 5 x 3).
9 times the number decreased by 13 is: 9x - 13.
Since they are equal, we have
5(x+ 3) = 9x - 13.
5x + 15 = 9x - 13
-4x + 15 = -13
-4x = -28
x = 7
