Question

NEED HELP FAST PLEASE!!!

Problem:

If you take an imagined number and add a zero to the right and subtract the result from 143, you'll get the tripled number. What is the imagined number.

Answer 1

143-10x=3x
143 = 13x
x = 143/13

Answer 2

x=11

Answer 3

Answer 4

was that fast enough?

Answer 5

Answer 6

11, add a 0 on the right:
110
Subtract the result from 143:
143-110 = 33 and u'll get triple the number. 33 = 11*3, that's right..
