15 + 1 = 16 sum 15 - 1 = 14 difference
The numbers are: 15 and 1 because 15+1 = 16 and 15-1 = 14
2 Numbers are a and b. We have( a>b) a+b=40(1) and a-b=10(2) a=10+b( from 2. Subtracts both side by b) => 10+b+b=40 (from 1. Substitute a with 10+b) => 10+2b =40 => 2b =30 => b =15 =>a=10+15=25 => a=25 b=15.
1 and 0 are the two whole numbers with their sum same as their difference
1.The sum of two numbers is 15. The difference of the same two numbers is 7. What are the two numbers? The sum of the two numbers is 15.x + y = 15The difference is 7.x - y = 7Now, solve by adding the two equations.Now, plugging into the first equation givesThe numbers are 11 and 4.
15 + 1 = 16 sum 15 - 1 = 14 difference
The numbers are 15 and 1
The numbers are: 15 and 1 because 15+1 = 16 and 15-1 = 14
15 + 1 = 16, and 15 - 1 = 14, so the two numbers are 15 and 1.
2 and 1 .their sum is 3 .difference is 1
2 Numbers are a and b. We have( a>b) a+b=40(1) and a-b=10(2) a=10+b( from 2. Subtracts both side by b) => 10+b+b=40 (from 1. Substitute a with 10+b) => 10+2b =40 => 2b =30 => b =15 =>a=10+15=25 => a=25 b=15.
The sum of the first 5 numbers is 15. 1+2+3+4+5=15
1 and 0 are the two whole numbers with their sum same as their difference
1.The sum of two numbers is 15. The difference of the same two numbers is 7. What are the two numbers? The sum of the two numbers is 15.x + y = 15The difference is 7.x - y = 7Now, solve by adding the two equations.Now, plugging into the first equation givesThe numbers are 11 and 4.
