Question

Are 9(4-x) and 36+9x equivalent expressions

Answer 1

No.

Explanation:

If you simplify the first problem, ( 9(4-x)) It would equal 36-9x. While they may be close one has an addition sign and the other has a minus sign.

Answer 2

No, they are not equal expressions

Explanation:

9(4-x)

Expanding the algebra

9(4)- 9(x)

36-9x is different from 36+9x because it has different signs.

An example is, let's assume x is 2, we would see that it won't give the same answer. If x is 2, then

36-9(2)

36-18=18

36+9(2)

36+18= 54

18 is not equal to 54

36-9x is not also equal to 36+9x
