How do I solve for the following:
Negative sixteen plus the quotient of a number and -4 is -3

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

What’s the equation you are trying to solve to get x?

Aand b are correctly balanced reactions. they have the same number of atoms in both sides of the reaction

Need the graph to answer this.
