Answer:
Y=7
Explanation:
First you need to distribute. This means you take the number outside of the parenthesis _( ) and multiply it by the numbers inside. So you would do:
9xY=9y
when multiplying by Y you just multiply by the amount of Y. Such as if it was 1x3y you would multiply 1x3. But when it just says Y that means there is only 1 y. So this is 9x1 and your answer is 9y.
9x-4=-36
So your new problem is:
9y-36=27
Now you need to get y alone. So to remove the 36 you need to do the opposite of what it needs in the problem. So in this case it asks you to subtract 36 so you need to add.
27+36=63
So then you have:
9y=63
then you need to divide to get the value of 1y.
63/9=7
so y=7!3
