Solving Systems Of Equations By Substitution Method In this method, we first find the value of one variable (y) in terms of another variable (x) from one equation. Substitute this value of y in the second equation. Second equation becomes a linear equation in x only and it can be solved for x. Putting the value of x in the first equation, we can find the value of y. This … [Read more...] about Solving Systems Of Equations By Substitution Method
