Question

Cheryl thinks that the
following expressions are
equivalent:
3x + 3 = 3 + 3x + 0
Is Cheryl right? If so,
prove that these two
expressions are
equivalent. If not, what
error(s) did Cheryl make?

Answer 1

Answer:

yes she is right

Step-by-step explanation:3x + 3 is the same as 3 + 3x.  

the zero adds nothing to the 3x term. So this means that 3x +3 and 3 + 3 are the same.
