Best ResponseYou've already chosen the best response.0kay all you have to do is just substitute one equation into the other. So just isolate any variable in one equation then substitute that into the second equation to solve for the other variable

Best ResponseYou've already chosen the best response.0k so for this question isolate x or y in any equation. I choose to rearrange the second equation. Rearrange (2) x  2y = 10 x = 2y  10 * multiply both sides by 1 x = 10  2y substitute x = 10  2y into equation (1) and solve for y
