Best ResponseYou've already chosen the best response.0subtract twice equation 1 from equation 2 and thrice equation 1 from equation 3. that should eliminate c and you will have two new equations with just a and b. solve for a and b and substitute their values in one of the original equations to get c

Best ResponseYou've already chosen the best response.0no you can manipulate them any way you like. subtraction is simply negative adding. 42 is 4+(2). Think about it this way then add negative twiceequation 1 from equation 2 and negative thrice equation 1 from equation 3. that should eliminate c and you will have two new equations with just a and b. solve for a and b and substitute their values in one of the original equations to get c
