River C : 200 + x
River D: x

200 + x + x = 5,540
combine like terms

200 + 2x = 5,540
subtract 200 from both sides

2x = 5,340
divide both sides by 2 to isolate the variable

x = 2, 670

River C: 200 + x = 200 + 2,670 = 2,870
River D: x = 2,670

2,870 + 2,670 = 5,540

Please help!!! trying to finish early
Scrat [10]
To solve this problem you must apply the proccedure shown below:

 The linear functions have the form y=mx+b

 where m is the slope and b is the y- intercept

 Therefore, you have:

 1) The slope -6/5 and b=(0,8) is:

 y=(6/5)x+8

 
2) You have 3x-2y=1. Then, you only have to clear y:

 y=(3/2)x-1/2
