Question

write an example of an algebraic expressions that always has the same value regardless of the value of the variable. Need help with hw please

Answer 1

For the algebraic expressions to have the same value regardless of the value of the variable, let the variable appear in both the numerator and the denominator. Example, 
                                       78x / 13x = 6
We can cancel the x's from both the numerator and denominator and the expression becomes, 6 = 6.
