Question #b8645 Algebra Systems of Equations and Inequalities Linear Systems with Addition or Subtraction 1 Answer Cesareo R. Feb 12, 2017 #{4,-1}# and #{10,2}# Explanation: Adding #x-2y=6# with #-x+2y^2-2# term to term we obtain #2y^2-2y=4# Solving for #y# we get #y = {-1,2}# and consequently #x = {4,10}# Answer link Related questions What if the elimination method results in 0=0?
