2y - 8x = 20
2y - 8x + 8x = 20 + 8x
2y = 20 + 8x
2 2
y = 10 + 4x

Pick a number. Any number. Call it 'x'.

Multiply 'x' by 4.
Add 10 to the product.
Call the current number 'y'.

The 'x' and 'y' that you have now are an 'answer' to that equation.

Do it as many times as you like. There are an infinite number of them.
