Evaluate Blue when z = 9
To do this, we simply substitute 9 for z in 

Convert indices to fraction


<em>Hence, the blue section has an area of </em>
<em></em>
Slimination
multiply first equaiton by 2
2x+6y=10
add to second equiaotn
2x-2x+6y-6y=10-10
0=0
this is true so therfor they are the same equaiton
so solve
x+3y=5
3y=-x+5
y=-1/3x+5/3
subsituter values for x and get valuse for y
if x=2 then y=1
