All I can tell you is 12x16=192
The case is about proportional relatioship so to slove it you have to do this.
45(V) ?
____ x ____
60(V) 15
45*15=675
60*?=60
675 DIVIDE BY 60=11.25
so the answer is 11.25
hope it help you
thank you

Alright, so 2x+2=0 (with x being the number) is what I'm getting from this. Subtract 2 from both sides to get 2x=-2, and then divide by 2 to get x=-1
Mult. the 2nd eqn by 6 and then add this "new" equation to the 1st given eqn:
-6x + y = -2
6x -18y = 54
--------------------
-17y = 52, or y = -52/17. Subst. this value of y into either equation to find the value of x.
