Answer:
Step-by-step explanation:
uhh ok I’ll give it a shot-
Formula:
9x - 42 = 5*
* = any digit that works ig
To do this I’m basically just going fill in x with a random digit, so the math, then see if the end # starts with a 5 (if that makes sense)
1. 9(11) - 42 = 5*
9 x 11 = 99
99 - 42 = 57
(Yay an answer)
2. 9(70) - 42 = 5*
9 x 70 = 630
630 - 42 = 588 (I don’t know if that’s allowed ♀️)
3. 9(71) - 42 = 5*
9 x 71 = 639
639 - 42 = 597
4. 9(69) - 42 = 5*
= 579
any number through 61 - 71 will probably work since those #’s times 9 - 42 are all start with 5.
