Answer:
Solution set = (-5, -2)
Step-by-step explanation:
Given equations;
-7x + 8y = 19 ------------- eq1
7x – 9y=-17 --------------- eq2
Adding both equations:
-y = 2
OR
y = 2
Put value of y in eq2:
7x - 9(-2) = -17
7x + 18 = -17
7x = -17 -18
7x = -35
x = -5
Solution set = (-5, -2)

Answer: 40kg
Explanation: If 40% water and 10% pulp (Total 50%) is 20kg
Then 90% water and 10% pulp (Total 100%) would be double, so therefore 40kg
To confirm: 10% = 4kg
40kg - 4kg = 36kg
to get from 90% to 40% just divide by 2.25
the answer is 16kg
add on the pulp weight of 4kg = 20kg
