Answer:
False
Step-by-step explanation:
It is given that Noah thinks :
9x - 2x + 4x = 3x as the subtraction sign after 9x tells us to subtract everything that comes after 9x.
This is wrong as according to the BODMAS rule, we have to do the addition operation first and then followed by subtraction operation.
That is
⇒ 9x - 2x + 4x
⇒ (9x -2x)+ 4x
⇒ 7x + 4x
⇒ 11x
Therefore the answer to the equation is 11x and not 3x.
