*id also like to know how you solved it
we can start with two variables \(x\) and \(y\)
they add to 1 so \(x+y=1\) they multiply to give \(-3\) so \(xy=-3\)
to make one variable out of this mess, \(x+y=1\) is the same as \(y=1-x\) put that in the second equation and get \[x(1-x)=-3\]
then solve that one

you good from there?
nope haha ive been out of school for a long time, i only come here to help friends usually
\[x(1-x)=-3\\ x-x^2=-3\\ x^2-x-3=0\] then use the quadratic formula to solve it
im working it for now
2.30277564, -1.30277564. it's of by 0.00000001 but its the right answer
