Well, what happened when you added the two equations?
Which statement matched your result ?
When you solve the system shown by the elimination method, which statement is true?
y + 3x = 10
−y − 3x = 10
A. You eliminate y; the sum of the coefficients of y is zero. Then, you can solve for x.
B. There is no solution; x and y are eliminated and you get the false statement 0 = 20.
C. There are infinitely many solutions; x and y are eliminated and you get the true statement 0 = 0.
D. You eliminate x; the sum of the coefficients of x is zero. Then, you can solve for y.
