Question

can algebraic expression be evaluated for specific values

Answer 1

We have learned that, in in an algebraic expression, letters can stand for numbers. When we substitute aspecific value for each variable, and then perform the operations, it's calledevaluating the expression. Let'sevaluate the expression 3y + 2y when 5 = y.

Answer 2

Technically, yes, but setting it equal to something will change it to an equation.

Like you could say 5x+4 as an expression, then x = 7, but saying 5x + 4 = 39 is no more an expression.

Unless the question is asking "can you solve an expression", which would be no because you can't solve unless you have two comparable values.
