u find the common denominator

Take the value of each variable in the expression and replace the variable by its value. Then do the math!

By eliminating or substituting one of the variables in the two equations in order to find the value of the other variable. When this variable is found then substitute its value into the original equations in order to find the value of the other variable.

Solving for one variable makes it easy to put in a value for the other variables, and find a value for the first variable.

No, because 'x' is a variable.
