Answer:
8x-y=19 is already in your Ax+By=C form
For your second one you need to switch your x and y around so
3x+y=7 gives you your Ax+By=C form
Now you want to use the system of elimination to solve the system of equations
So when you take 8x-y=19 you then add 3x+y=7
8x+3x= 11x
-y+y=0 (crosses out... why it's called elimination)
19+7=26
Your equation is now 11x=26
You then divide both sides by 11 to get
x=26/11
(Hope this helps ya ;)
For Example 3 :
First blank is cos (theta)
Second blank is sec(theta)
For Example 4 :
First blank is (x^4)/(2) - (3x^2)
Second blank is 0
Third blank is -4
Fourth blank is 0.4286
Hope this helps :)
