what are the coordinates? for y=2x-5 x-2y=-8
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
yeah you want to solve for x correct?
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
