hi...
i need help finding 2 equations that i would use for this elimination process....
this is what they gave me:
* the sum of the digits i a two-digit is 14. If the 2 digits are reversed, the new number is 18 less than the original number. Find the original number.
what two equation would i use for this???

number is ab which is b + 10 a if base ten system
a + b =14 equation one
new reversed number is ba which is a +10 b if we are doing decimal and not binary or octal or something
a + 10 b + 18 = b + 10 a
9 b + 18 = 9 a
a - b = 2 equation two
a + b =14 equation one
new reversed number is ba which is a +10 b if we are doing decimal and not binary or octal or something
a + 10 b + 18 = b + 10 a
9 b + 18 = 9 a
a - b = 2 equation two
