Answer:
The original number is 83
Step-by-step explanation:
let the number be ab
Sum of the two is 11
a + b = 11
tens digit a is one less than 3 times the ones digit
3b - a = 1
a = 3b - 1
3b -1 + b = 11
4b = 11 + 1
4b = 12
b = 12/4
b = 3
a = 3b - 1
a = 3(3) - 1
a = 9-1
a = 8
A(b+c) = ab + ac
5(3x + 5) = 15x + 25
