Question

what are the coordinates? for
y=2x-5
x-2y=-8

Answer 1

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.

Answer 2

Understand how I plugged that in? :o

Answer 3

yeah you want to solve for x correct?

Answer 4

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.

Answer 5

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