Full solution

Q. Solve.\newlinex=4x = -4\newline3x7y=9-3x - 7y = -9\newline(_____, _____)
  1. Substitute x=4x = -4: Substitute x=4x = -4 into the equation 3x7y=9-3x - 7y = -9 and then simplify.\newlineSubstitute 4-4 for xx in 3x7y=9-3x - 7y = -9.\newline3(4)7y=9-3(-4) - 7y = -9
  2. Calculate and simplify: Calculate the multiplication and simplify the equation.\newline127y=912 - 7y = -9
  3. Isolate variable term: Isolate the variable term 7y7y. Subtract 1212 from both sides of the equation. 127y12=91212 - 7y - 12 = -9 - 12 7y=21-7y = -21
  4. Solve for y: Solve for y.\newlineDivide both sides by 7−7.\newline7y/7=21/7−7y / −7 = –21 / −7\newliney=3y = 3
  5. Find ordered pair: We found:\newlinex=4x = -4\newliney=3y = 3\newlineWhat is the solution in the form of an ordered pair?\newlineSubstitute x=4x = -4 and y=3y = 3 into (x,y)(x, y).\newlineThe solution is (4,3)(-4, 3).
