Follow the order of operation: PEMDAS

Parenthesis
Exponents (and roots)
Multiply
Divide
Add
Subtract

3 x (7-2) + 4

first do Parenthesis (as it shows up first)

7 - 2 = 5

Next, Multiply (the next one you have to do)

5 x 3 = 15

Finally, add

15 + 4 = 19

B. 19 is your answer

hope this helps

X-b=a solve for x please show work tnx

Okay so, you would just have to simply do one step for this literal equation. 

x-b=a
  +b +b 
x=a+b

You would just have to add b to both sides to cancel out the -b on the left side because you have to isolate x to solve for x. So you add b to both sides, and then the -b gets cancelled out and the right side becomes a+b. 

So x = a+b 

Hope this helped!
