A certain three-digit number equals fifteen times the sum of its digits. if its digits are reversed, the resulting number exceed
s n by 396. the one’s digit is one larger than the sum of the other two. give a linear system of three equations whose three unknowns are the digits of n. solve the system and find n.
Lets see a and b are legs c=hypotnuse a^2+b^2=c^2 10^2+b^2=10^2 100+b^2=100 minus 100 both sides b^2=0 b=0 false, if you have a leg legnth 0, then they lines are right on top of each other
