Question

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

The sum of two numbers is 170 and their difference is 26.

Answer 1

x+y=170
x-y=26

Answer 2

Let the two numbers be x and y.

x + y is given as 170, so we put x + 7 = 170.

The difference is 26, so we put x - 7 = 26

That is the system of two equations.

Answer 3

ok typos:

Let the two numbers be x and y.

x + y is given as 170, so we put x + y = 170.

The difference is 26, so we put x - y = 26

That is the system of two equations.

Answer 4

Note, that we could also frame the system as:

y + x = 170
y - x = 26
