What is the value of the y-coordinate of the solution to the system of equations?

\[ x - 2y = 1 \]

\[ x + 4y = 7 \]

\left\{\begin{array}{ccc}x-2y=1\\x+4y=7&/\cdot(-1)\end{array}\right\\\\+\left\{\begin{array}{ccc}x-2y=1\\-x-4y=-7\end{array}\right\\-----------\\.\ \ \ \ \ \ \ \ \ -6y=-6\ \ \ \ \ /:(-6)\\.\ \ \ \ \ \ \ \ \ \ \ \ \ \ y=1\\\\x-2\cdot1=1\\x-2=1\\x=1+2\\x=3\\\\Answer:\\\left\{\begin{array}{ccc}x=3\\y=1\end{array}\right

x - 2y = 1

(-x - 4y = -7)


-6y = -6
-6 -6
We divide -6 both sides of the equation in order to get our answer.
y = 1 ;

The y-coordinate of the solution to the system of equations is 1. By substituting values and solving simultaneously, we found the point of intersection, which is (3, 1). Thus, the corresponding y-coordinate is 1.
