WebSep 17, 2024 · First, lets add the first and last equations together, and write the result as a new third equation. This gives us: b + g + r = 30 − 2 g + r = 0 2 g + 2 r = 30. A nice feature of this is that the only equation with a b in it is the first equation. Now let’s multiply the second equation by − 1 2. This gives.
