Question

Which of the following operations will change the solution of the system x − y = 2 and 3x − 3y = 2?

Answer 1

i think righ answar 3 multyply both side (3) ans

Answer 2

Answer:

Step-by-step explanation:

the system consists of two parallel lines which means that there are no solutions. if you change the second equation to 3(x - y) = 6 then the system Will consist of two identical lines which means infinity of solutions. now to get a unique solution you cant for exempel change x - y = 2 to x + y = 2.
