The expression $x+3$ is in (a) one variable.

To Find: The type of expression on the basis of variables

• We know, Variable is any assumed symbol or letter that can have any undefined value. For Example: $a,b,c,x,y\ etc.$ The number of variables in a given expression determine the type of expression if it is one variable, two variable or no variable.
