Myra is evaluating the expression - 31.7 + 4.5x, when x = 2.1. - 31.7 + 4.5 (2.1) - 27.2 (2.1) - 57.12 What was Myra's error?

-31.7 + 4.5 (x) = - 22.25

1) You put the number of what x=in ()

2) You multiply 4.5*2.1 first

3) Then you subtract 31.7

The answer is going to be A, because B=C

If u do the steps for B your answer is C

But to be honest B and c are wrong you suppose to replace X with whatever X =
