-2x+9y=5 when x equals 11

1 answer:

6 0

You would multiply -2 by 11 and get -22. Next your equation would equal to -22+9y=5. You simply subtract -22 from both sides, which basically means you're adding 22. Next your equation would be 9y=27. All that is left to do is divide both sides by 9, and you get that y is equal to 3.
