(1) If the degree of an equation is one then it is called a
(2) If a linear equation has only one variable then it is called a linear equation in
(3) The value which when substituted for the variable in the given equation makes L.H.S. = R.H.S. is called a solution or
(4) Just as numbers, variables can also be transposed from one side of the equation to the other side.
