Q. Solve using elimination.\newline−10x+4y=18-10x + 4y = 18\newline6x−4y=−66x - 4y = -6\newline(_____, _____)
  1. Eliminate y: Add the two equations to eliminate y.\newline−10x+4y=18-10x + 4y = 18\newline6x−4y=−66x − 4y = −6\newline(−10x+4y)+(6x−4y)=18+(−6)(-10x + 4y) + (6x - 4y) = 18 + (-6)\newline−4x=12-4x = 12
  2. Solve for x: Solve for x.\newline−4x=12-4x = 12\newlinex=12−4x = \frac{12}{-4}\newlinex=−3x = -3
  3. Find yy: Substitute x=−3x = -3 into the first equation to find yy.
    −10(−3)+4y=18-10(-3) + 4y = 18
    30+4y=1830 + 4y = 18
    4y=18−304y = 18 - 30
    4y=−124y = -12
  4. Solve for y: Solve for y.\newline4y=−124y = -12\newliney=−12/4y = -12 / 4\newliney=−3y = -3
