Answer:

-1

Step-by-step explanation:

4x+5y=7

3x-2y= -12

To get the opposite coefficient, we multiply by -1

-1(4x+5y=7 )

-4x-5y = -7

-1*(3x-2y= -12)

-3x +2y = 12

Both equations now have the opposite coefficients on both x and y.

The absolute value of a number is its distance from 0. An easy way to think about this is that the absolute value turns a negative number positive, and has no effect on positive numbers. In this case, we are taking the absolute value of a negative number. This means we should simply make the number positive. Therefore, the answer is $\frac{1}{3}$
