Full solution

Q. Solve using elimination.\newline6x−4y=−206x - 4y = -20\newline6x−6y=−186x - 6y = -18\newline(_____, _____)
  1. Subtract and eliminate xx: Subtract the second equation from the first to eliminate xx:
    (6x−4y)−(6x−6y)=−20−(−18)(6x - 4y) - (6x - 6y) = -20 - (-18)
    0x+2y=−20x + 2y = -2
    Simplify:
    2y=−22y = -2
  2. Solve for y: Solve for y:\newliney=−22y = \frac{-2}{2}\newliney=−1y = -1
  3. Substitute and find xx: Substitute y=−1y = -1 back into the first equation to find xx:6x−4(−1)=−206x - 4(-1) = -206x+4=−206x + 4 = -206x=−246x = -24
  4. Solve for x: Solve for x:\newlinex=−246x = -\frac{24}{6}\newlinex=−4x = -4
