What is x + y = 2 ?

The equation x + y = 2 means that the sum of x and y equals 2.

There isnt just one answerthere are infinitely many pairs of numbers that satisfy it. For example:

• x = 0, y = 2
• x = 1, y = 1
• x = 2, y = 0
• x = -1, y = 3
• x = 4, y = -2

All of these work because when you add x + y, the result is 2.

You can also write one variable in terms of the other:

• y = 2 x
  or
• x = 2 y

This is a linear equation, and if you graph it, it forms a straight line.
