What is the answer to the question

12

Step-by-step explanation:

{3 x [30 - (4 x 7)]} x 2

PEMDAS stands for parenthesis, exponents, multiplication/division, and addition/subtraction. So, we have to start by doing the innermost parenthesis, which here is 4 x 7.

{3 x [30 - (28)]} x 2

Now we still have more parenthesis, so what we have to do is work out way out. The next parenthesis we have to solve is 30 - 28

{3 x [2]} x 2

Now, we need to solve the last parenthesis, 3 x 2

{6} x 2

And lastly, finish by multiplying 6 x 2
