Systems of equations that have the same solution are called equivalent systems. Given a system of two equations, we can produce an equivalent system by replacing one equation by the sum of the two equations, or by replacing an equation by a multiple of itself.

To combine two equations, add the left sides together, and add the right sides together. If you set your equation up right, one of the variables should cancel. Here's an example using the same equations as the last step: Your equations are 6x - 2y = 6 and -x + 2y = 4.

The answer to the original question 'Is it possible to solve for two variables related by single equation' is, YES! Solution As x,y are real numbers, either y?1?0 or 1?y?0.

Do unto one side of the equation, what you do to the other! An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced.

Two or more linear equations that all contain the same unknown variables are called a system of simultaneous linear equations. Solving such a system means finding values for the unknown variables which satisfy all the equations at the same time.
