40 = 0.5r
40/0.5 = r
80 = r
just divide the number in front of the r so that you can figure it out
2040. 10 times 4 is 40. If it happens every ten years then when the Olympics happen 10 times it would be 2040.

Hi there!

For a system to have infinite solutions, the lines have to be the same. We can begin by rearranging the given equation into the format y = mx + b:
2y - 4x = 6
Move x to the opposite side:
2y = 4x + 6
Divide all terms by 2:
y = 2x + 6
The answer choice that matches this is the first one.
