What do you think will it be?

parthkohli · Answer

It's the multiplication of 4 and (x + 2).
PEMDAS says that multiplication should be done first.
So, you should apply distributivity.

Distributivity says:


$\Large \color{MidnightBlue}{\rightarrow a(x + y)  = ax + ay }$

parthkohli · Answer

So, 4(x + 2) = 4x +  4(2)

4x+8=10+x

If you're solving for x, you would subtract 8 to both sides and subtract x from both sides

3x=2
Divide by 3
x=2/3

Parenthesis > Exponent > Multiplication/Division > Addition/Subtraction

Answer is A :D
