Full solution

Q. Solve.\newliney=−9y = -9\newline8x+7y=178x + 7y = 17\newline(_____, _____)
  1. Substitute y=−9y = -9: Substitute y=−9y = -9 into the equation 8x+7y=178x + 7y = 17 and then simplify.\newlineSubstitute −9-9 for yy in 8x+7y=178x + 7y = 17.\newline8x+7(−9)=178x + 7(-9) = 17
  2. Simplify by multiplying: Simplify the equation by multiplying 77 by −9-9. 8x−63=178x - 63 = 17
  3. Isolate variable term: Isolate the variable term by adding 6363 to both sides of the equation.\newline8x−63+63=17+638x - 63 + 63 = 17 + 63\newline8x=808x = 80
  4. Solve for x: Solve for x by dividing both sides of the equation by 88.\newline8x8=808\frac{8x}{8} = \frac{80}{8}\newlinex=10x = 10
  5. Find ordered pair: We found:\newlinex=10x = 10\newliney=−9y = -9\newlineWhat is the solution in the form of an ordered pair?\newlineSubstitute x=10x = 10 and y=−9y = -9 into (x,y)(x, y).\newlineThe solution is (10,−9)(10, -9).
