The answer is X=1, y=5. X=-5 y=-1
In the question, the given expression is

And we have to find the equivalent expression to the given expression .
First we remove the parenthesis

Now we combine the like terms, and here like terms are z and z, therefore on combining , we will get

And that's the required equivalent expression .
Let's get the data out of the problem:
Nv = 18
Ov = 12
Now, we can apply in this equation that relates the new and the old values:
i = Nv / Ov
i = 18 / 12
i = 1.5
Now, we just consider what has passed from 1, and this is 0.5, converting to percentage it is:
p = 0.5 . 100
p = 50%
The increase was 50%.
Hope it helps.
Multiply 3 & 70 and divide by the answer of 6'1 6'4 you multiply them then your answer
