Question

D. 9 + y = 6x and 6x - y = 9 has an infinite number
of solutions.
True
False

Answer 1

The answer for this question is (True)

Answer 2

True

Explanation:

9 + y = 6x -> y = 6x - 9

6x - y = 9 -> y = 6x - 9

A solution occurs whenever there is a value for x that can solve both equations.

The equations are the same.

If you plotted them on a graph they would overlap and there would be a straight diagonal line going on forever.

So there are infinitely many solutions.
