## krissywatts 3 years ago what are the coordinates? for y=2x-5 x-2y=-8

1. zepdrix

Let's solve this system using substitution. $\large \color{royalblue}{y=2x-5}$$\large x-2\color{royalblue}{y}=-8 \qquad \rightarrow \qquad x-2\color{royalblue}{(2x-5)}=-8$ From here, we can solve for x since that is the only variable in our equation.

Understand how I plugged that in? :o

3. krissywatts

yeah you want to solve for x correct?

4. zepdrix

yes c: If we solve for x, we can plug that x value into one of the two equations to find a corresponding y value. That will be the coordinate pair we were looking for.

i get (6,7) :) thanks for your help
