Step-by-step explanation:
x + y = 3 ---------------- eqn 1
y = -6x + 3 ------------- eqn 2
Substitute y for -6x + 3 in equation 1
x + -6x + 3 = 3
x - 6x + 3 = 3
-5x + 3 = 3
Collect like terms
-5x = 3 - 3
-5x = 0
Divide both sides by -5
x = 0

Answer:
Amount of fresh water = 3.5 * 10^7 cubic kilometers
Step-by-step explanation:
Given the following
Total water on earth = 1.4×10^9 cubic kilometers
If 2.5% of it is fresh water
Amount of fresh water = 2.5% of 1.4×10^9
Amount of fresh water = 0.025 * 1.4×10^9
Amount of fresh water = 0.035 * 10^9
Amount of fresh water = 3.5 * 10^7 cubic kilometers
