Mr. & mrs. jones just gave birth to fraternal twins- bob and jane. unfortunately, the nurse has confused the jones twins with 4 other babies and mr. and mrs. jones. which of the following 6 children are mr. and mrs. jones twins?

the wires in the toaster turning red and the toast crisping and turning brown

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
