21(11 +3x) or simplified more, would be: 231 + 63x
Step-by-step explanation:
P E M D A S
First, Do what is in the parethesis
7 x 3(5 x 2 + 3x + 1)
7 x 3(10 + 1 + 3x)
7 x 3(11 +3x)
Since there are no exponents move on to the next step.
Then multiply.
21(11 + 3x)
I didn't know whether if you were trying to put 5x(2) or not, so it got me confused! Sorry if this isn't right equation! But I hoped this helped!
If simplifies even more, it would be
231 + 63x
(If they wanted it to be in simpilest form)
