what is equivalent equation. 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. Well theyre telling us for the solution to this equation X plus 2y is equal to negative one so negative one is the same thing as X plus 2y for that solution so were not gonna change the resulting solution of the system so its a completely legitimate operation what Vivek did is adding the left-hand sides and adding the right-hand sides to.

For example 24 and 36 both are equal to ½. But if the values are plugged in the expression both the expressions give the same result. 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. For example 24 and 36 both are equal to ½.
