Answer:
We can solve the equation of two unknown variables for one variable in terms of second variable.
Step-by-step explanation:
We know that, an equation with a variable can be solve easily. But in the case of two unknown variables, we can solve the equation for one variable in terms of second variable. For example:
If we have given an equation with two unknown variable x+y=4, we can solve this equation for variable y in terms of variable x or we can solve this equation for x in terms of y. Which could be written as:
y=4-x
or
x=4-y.
