See this is s equation.

-6y=-42

Now, we know that if we multiply -1 to a negative no, the minus signs cancel, right?
Here, cancel the negative sign on both sides like that, we get:

6y=42

Then, multiply both sides by 1/6, we can do this since the equaiton remains same if you add, multiply, divide the equation on both sides by the same number.

So, when you do that, weget:

6y*1/6= 42*1/6

=>y=42/6

=>y=7

So, y=7 is the answer.

hope this helps!
