Answer:
-3/2
Step-by-step explanation:
If the first equation is 9x +3/4y = 6, then the solution would look like this:

An appropriate multiplier is -3/2.
Answer:
One example is the equation:
2x + 6 = 4x/2 + 12/2
To solve this, we need to transpose like terms to the same side.
2x - 4x/2 = 12/2 - 6
2x - 2x = 6 - 6
0 = 0
Since both sides are zero, it means that the equation has infinite number of solutions.
