Write a system of equations using x and y in each for the following

1.) the sum of two numbers is 170 and their difference is 26

2.) the sum of two numbers is 170 and their difference is 26, show how to solve this using any method

3.) the sum of two numbers is 170 and their difference is 26 write the solutions as an order pair

1) x+y = 170

x-y = 26

2) Subtract the two equations from each other. Doing this you get 2y = 56.

So the value of y is 28. Then plug in the value of y into any of the two equations and solve for x.

x-28 = 26

x = 54

3) When writing solutions as an ordered pair, the x value always comes first followed by the y value. So it would be (54, 28).
