99 points solve the system using elimination. show your work. 2x – 3y = 18 x + y = 14 check my answer. solve the system using substitution. x = y – 3 2x + 4y = 16 substitute x for y-3 to get y: 2x + 4y = 16 2(y-3) + 4y = 16 2(y) 2(-3) +4y (distribute) = 2y -6 +4y 2y - 6 +4y (combine like terms) = 6y -6 6y -6 +6 = 16 +6 (get rid of -6)= 6y=22 6y/6=22/6 (get y)= y=3.6 substitute y for 3.6 to get x: x = y-3 x = 3.6 - 3 = 0.6 x = 0.6 final: (0.6, 3.6)
