Practice problem
If α\alphaα is a real variable, solve for xxx and yyy in terms of α\alphaα. 2x+αy=22x+\alpha y=22x+αy=2 2x+(α−1)y=−22x+(\alpha-1)y=-22x+(α−1)y=−2
x=1−2αx=1-2\alphax=1−2α , y=4y=4y=4
x=αx=\alphax=α , y=4y=4y=4
x=1−αx=1-\alphax=1−α , y=4y=4y=4
x=2−3αx=2-3\alphax=2−3α , y=4y=4y=4
Type a concept, like “slope” or “photosynthesis”.
