Question

When you solve the system shown by the elimination method, which statement is true?

y + 3x = 10
−y − 3x = 10

Answer 1

B. There is no solution; x and y are eliminated and you get the false statement 0 = 20.

Explanation:

According to the elimination method, the two equations are

y + 3x = 10

−y − 3x = 10

If we solve it

0 = 20

As x and y would be eliminated due to positive and negative signs

Therefore the option b is correct
