Practice problem
Solve for xxx and yyy in terms of the nonzero variables α\alphaα and β\betaβ. αx+2βy=7\alpha x + 2\beta y=7αx+2βy=7 3αx−2βy=53\alpha x - 2\beta y = 53αx−2βy=5
(α,β)(\alpha, \beta)(α,β)
(α,1β)\left(\alpha ,\frac{1}{\beta}\right )(α,β1)
(4α,12β)\left(\frac{4}{\alpha} ,\frac{1}{2\beta}\right )(α4,2β1)
(3α,2β)\left(\frac{3}{\alpha} ,\frac{2}{\beta} \right)(α3,β2)
Type a concept, like “slope” or “photosynthesis”.
