Im GOING TO GIVE YOU BRAINLIEST PLZ HELP

PEMDAS stands for the order to solve operations.

P is for parenthesis (or brackets), solve this first.
E is for exponents, solve this next.
MD is for multiplying and dividing.
AS is for adding and subtracting, this is done last.

a:
7 + 3 * 5 - 4 / 2 + 3
7 + 15 - 2 + 3
22 + 1
23

b:
[(7+3) * 5 - 4] / 2 + 3
[10 * 5 - 4] / 2 + 3
[50 - 4] / 2 + 3
46 / 2 + 3
23 + 3
26

I hope this helps you!

You would need a laid out graph for this but could you provide a picture of just a graph? i can give stepssolve for y.subtract 4xdivide by -1 (opposites)graph slope intercept formcheck each point to see if it’s on the graph
