Ryan is trying to determine whether 2.7x-5.9 is equivalent to 2.8x-5.9. To test this, he substitutes 0 for X into both expressions. Explain why this will not give him the correct answer

The coefficients of x are different in the expressions, but the constant values are the same. Zero times any value is zero, so both expressions will be equal to –5.9. If Ryan tried any other number, he would see that the expressions are not equivalent.

Step-by-step explanation:

This won't give him the correct answer because if he substitutes zero into anything he will get -5.9. 0 multiplied by anything is 0 and if you put that into bot equations you get the same answer so it won't help him. he should instead try 1 or something like that.
