Y=47/7
A mathematical expression does not have an answer, if it is algebraic and all of the terms are unlike. For example, x+7y does not have an answer because there are no definite solutions, and there is no possibility to combine like terms. However, the expression 2x+7y+3x does have an answer, but the solution is merely the combination of like terms. (5x+7y)
4x + 3y - 2x - 7y2x - 4y
If you mean: 13x+2y-10x-7y then it is an algebraic expression that can be simplified to 3x-5y
It is an algebraic expression which cannot be evaluated without information about y.
