X = 10y = x + 21The solution to the given system of equations is (x, y). What is the value ofy?
Question
X = 10y = x + 21
The solution to the given system of equations is (x, y). What is the value of y?
Solution
To find the value of y, we need to solve the system of equations given. Here are the steps:
-
The first equation is X = 10y. We can rewrite this as x = 10y.
-
The second equation is y = x + 21.
-
Since x = 10y from the first equation, we can substitute x in the second equation with 10y. So, the second equation becomes y = 10y + 21.
-
To solve for y, we can subtract 10y from both sides of the equation to get -9y = 21.
-
Finally, we divide both sides of the equation by -9 to solve for y. So, y = 21 / -9 = -7/3.
So, the value of y is -7/3.
