x + y = 50
x - y = 16
--------------- (add the two equations to solve for x)
2x = 66
x = 33
then substitute x into one of the above equations to get y = 17

If the problem of 2 numbers is between 30 and 40 and the difference between the two numbers is 5 what are the two numbers?
I think you mean product... 4 and 9
What has a difference of 6 and a sum of 14?
Suppose the two numbers are X and Y Then X - Y = 6 and X + Y = 14 Adding the two equations gives 2X = 20 so that X = 10 And substituting this value into one of the equations, Y = 4 The two numbers are 10 and 4.
How would solving a literal equation differ from a one or two step equation?
The difference is that first you have to understand the problem and translate it into an equation (or equations).
What is the sum of two numbers is 18 their difference is 2 what are the two numbers?
Let's call the two numbers x and y. We know that x + y = 18 and x - y = 2. We can solve this system of equations by adding the two equations together to eliminate y, which gives us 2x = 20. Dividing both sides by 2, we find that x = 10. Substituting this value back into one of the equations, we can solve for y and find that y = 8. Therefore, the two numbers are 10 and 8.
What is the difference between 2 and 1 step equations?
The difference between a one step problem, and a two step problem is very simple. It refers to the amount of effort and steps that are in your problem. For example, 3x=5, is a one step equation. 3x-7=5, is a two step equation.

The sum of two numbers is 50 their difference is 10 What is the number?
You can experiment with different numbers (trial-and-error). You can also write this as simultaneous equations: a + b = 50 (the sum of the two numbers is 50) a - b = 10 (the difference is 10) There are several approaches to simultaneous equations; in this case, it is easy to solve by adding the two equations together: a + b + a - b = 60 2a = 60 a = 30 So, the first number is 30. You can get the second number by replacing in any of the original equations.
What two numbers equal 5 and have a difference of 0.5?
Since the sum of two numbers is 5, we have:x + y = 5 where x and y are unknowns.Since the difference of two numbers is 0.5, we have:x - y = 0.5These are the two equations we obtain from interpreting the problem:x + y = 5x - y = 0.5Combine these equations to get:2x = 5.5x = 5.5/2x = 2.75Finally, substitute the value for either of the equation and solve for y.2.75 + y = 5y = 5.00 - 2.75y = 2.25So the two numbers with the sum 5 and the difference 0.5 are 2.75 and 2.25.
The sum of two numbers is 36 There difference is 24 Find the numbers?
This is a good exercise in building and solving a set of equations. Let X and Y be the two numbers. Then you are told their sum is 36, so write; X + Y = 36 Then you are told their difference is 24, so write; X - Y = 24 Now elliminate Y by adding the two equations; 2X = 60 and X = 30 . Now you can find Y by substituting this answer into either of the two original equations to get Y = 6.
The Sum of two numbers is 40and their difference is 10. What are the two numbers?
To determine the two numbers, assume the numbers to be 'x' and 'y'. Now, given that the sum of the numbers is 40. Therefore, x + y = 40 --> (A) Also, given that the difference of the numbers is 10. Therefore, x - y = 10 --> (B) Add the equations (A) and (B): 2x = 50, which gives x = 25. Use any of the equations above to determine 'y'. Using equation A: 25 + y = 40, which gives y = 15. Therefore, the numbers are 25 and 15.
Find two numbers whose sum is 23 and whose difference is 7?
x + y = 23x - y = 7Add the equations:2x = 30x = 15Subtract the equations:2y = 16y = 8
What has a difference of 6 and a sum of 14?
Suppose the two numbers are X and Y Then X - Y = 6 and X + Y = 14 Adding the two equations gives 2X = 20 so that X = 10 And substituting this value into one of the equations, Y = 4 The two numbers are 10 and 4.

What is the sum of two numbers is 18 their difference is 2 what are the two numbers?
Let's call the two numbers x and y. We know that x + y = 18 and x - y = 2. We can solve this system of equations by adding the two equations together to eliminate y, which gives us 2x = 20. Dividing both sides by 2, we find that x = 10. Substituting this value back into one of the equations, we can solve for y and find that y = 8. Therefore, the two numbers are 10 and 8.

What two numbers have a sum of 77.95 and a difference of 30.61?
It is better is we show you how to do this. Let the two numbers be a and b Then a + b = 77.95 And a - b = 30.61 Add these two equations: ==> 2a = 108.56 ==> a = 54.28 ==> b = 23.67
