Q. Solve.\newline−9x+8y=−11-9x + 8y = -11\newliney=−7y = -7\newline(_____, _____)
  1. Substitute y=−7y = -7: First, we substitute y=−7y = -7 into the equation –9x+8y=–11–9x + 8y = –11. This gives us –9x+8(−7)=–11–9x + 8(-7) = –11. After simplifying, we get –9x−56=–11–9x - 56 = –11.
  2. Add 5656 to isolate −9x-9x: Next, we add 5656 to both sides of the equation to isolate −9x-9x. This gives us −9x=−11+56-9x = -11 + 56. After simplifying, we get −9x=45-9x = 45.
  3. Divide by −9-9 for xx: Finally, we divide both sides of the equation by −9-9 to solve for xx. This gives us x=45−9x = \frac{45}{-9}. After simplifying, we get x=−5x = -5.
  4. Substitute values for coordinate point: We found y=−7y = -7 and x=−5x = -5. Substitute these values in (x,y)(x, y) to get the coordinate point.\newlineThis gives us the coordinate point (−5,−7)(-5, -7).
