Full solution

Q. Solve.\newliney=−1y = -1\newline−2x−4y=8-2x - 4y = 8\newline(_____ , _____)
  1. Plug y=−1y = -1: Plug y=−1y = -1 into the second equation.\newline−2x−4(−1)=8-2x - 4(-1) = 8
  2. Simplify the equation: Simplify the equation. −2x+4=8-2x + 4 = 8
  3. Subtract 44: Subtract 44 from both sides.\newline−2x=8−4-2x = 8 - 4
  4. Finish the subtraction: Finish the subtraction.\newline−2x=4-2x = 4
  5. Divide both sides: Divide both sides by –2–2 to solve for xx.x=4–2x = \frac{4}{–2}
  6. Calculate the value of x: Calculate the value of xx.x=−2x = -2
  7. Solution is (−2,−1)(-2, -1): Now we got x=−2x = -2 and y=−1y = -1. The solution is (−2,−1)(-2, -1).
