A:
Answer:x = 3 y = 21 (3,21) and if u want slope it will be 7 :DStep-by-step explanation:y = 10x - 9y = x + 181. Substitute for the y10x - 9 = x + 182. Add 9 onto both sides10x - 9 + 9 = x + 18 + 910x = x + 27 3. Subtract x on both sides10x -x = x - x+ 27 9x = 274. Divide by 9 on both sides9x/9= 27/9x = 3 __________________________________________________________Now that you have x, substitute that into one of the equationsy = x + 18y = 3 + 18 y = 21 or Β y = 10x - 9y = 10(3) - 9y = 30 - 9y = 21there both the same__________________________________________________________x = 3 y = 21Hope this helped!
