## ParthKohli 3 years ago Why is $$\rm \large x$$ mostly used as a variable?

1. anonymous

x marks the spot

2. anonymous

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

3. anonymous

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
