1. S (integral), pie 3.14, I didn't have a pie sign.
The R should be under the SS

S 0 to 2 S 0 to pie/2 x sin y dy dx


2. S 0 to 2 S 0 to 1 (2x + y)^ 8 dx dy


3. SS (6x^2y^3 - 5y^4) dA, R= {(x,y)| 0 <= x <= 3, 0 <=y<=1}
R

4. SS xye^x^2y dA, R= [0,1] x [0,2]
R

it says to solve the equation and write a reason for each step.

44-2(3x+4)=18x

4(5x-9)=-2(x+7)

2x-15-x=21+10x

3(7x-9)-19x=-15
