Yes, an expression can have more than one variable.
yes it can I've done a few experiments that have had more than one independant variable.
they have different proportions because one is bigger than the other one
No.
more than one variable
Yes, you can have more than one variable

Simultaneous equation* * * * *No, simultaneous equations are two or more equations that have all to be true at the same time (simultaneously) for the solution.An equation with more than one variable is a multivariate equaion.Area = 0.5*Length*Height or a = 0.5*l*h for the area of a triangle has more than one variables, but it is certainly not simultaneous.An equation with a variable is called a single variable equation. An equation that has more than one variable is called as a multi-variable equation. A polynomial equation has one variable in different powers: a common example is quadratic equations.
An equation with more than one variable is called a multivariate equation.
A variable can not hold more than one value at any given moment in time. It would have only one. If you wanted more than one value, you would have to make the variable an array.
if you change more than one variable, you will not know which one has had an effect on the experiment. If the outcome changes when one variable is altered, then the change can only be due to the one variable, by logical deduction.
You can have more than one variable, but it would take longer to solve.
A variable measured at the interval or ratio level can have more than one arithmetic mean.

No.
Actually, you have two - dependent and independent. But, you only have one variable because otherwise the answer wouldn't be accurate if you had more than one variable.
