## ParthKohli Group Title Why is $$\rm \large x$$ mostly used as a variable? one year ago one year ago

x marks the spot

well i think because of its commoness,also in graphs,cartesian plane.so we can manipulate x as a point in plane but a,or b can be tricky if you desire a slid solution

variable,x changes we can obseve y

So you are saying that $$\large \rm x$$ is used often because it is used often?

no i am saying using x in algebra can help us solve problems in algebra with function ,linear programming ,calculus because they already use x and f(x) as a function,wich defines a plane
