Vas happenin!!!
So you plug in the 3 into the equation 12-3(3)/2 + 3 [2(3)-4/3
You multiply the parentheses first
3 times 3 is 9
2 times 3 is 6
Then you plug it in again 12-9 / 2 plus 6-4/3
12-9 is 2/2 which is 1
1 plus 6-4/3
6-4 is 2
2/3 is you can stay it as a fraction or the decimal form is 1.5
1 plus 1.5 is 2.5
So your answer in decimal form is 2.5
Fraction form is 2 1/2
Hope this helps *smiles*
Sorry if it’s wrong
