Weegy: There is no solution as 1st equation we can say is 6x + 3y = 6 and the second says 6x + 3y = 12. We know that this cannot have two solutions.
User: Which pair of terms contain opposite coefficients?
3 and –3
–3 and –3
3x and 3x
–3x and 3x Weegy: -3x and 3x. A number and coefficient means there is a variable and a number. If it's opposites, then that means one has to be negative.
