-2x+9y=41.... equation 1
-2x-5y=1 ....equation 2
________________
14y=43
y=43/14
y=43/14 in equation 1
-2x+9(43/14)=41
-2x+387/14=41
-2x=41-387/14
-2x=187/14
x=187/-28
x=187/28 , y=43/14
if you want to check your answer
-2(187/28)+9(43/14)=41
Answer:
720g is your answer friend.
Step-by-step explanation:
- The total weight of large marbles = 6×70=420g
- The total weight of small marbles = 6×50=300g
- The total weight of 12 marbles = 420+300=720g

Seems like you forgot to attach the table.
For this reason, I will explain how to solve this question and you can apply using the numbers in your table.
We are given that:
y is inversely proportion to x. This means that as y decreases, x increases and vice versa.
Writing this into equation, we would get:
y = c/x where c is the constant of proportionality.
Now, we have the constant of proportionality given as 4.5.
This means that the equation that relates x and y is:
y = (4.5) / x
So, to fill in the table, we would substitute with the given x or y in the equation above and solve for the other variable.
Examples:
If given that x=2, then:
y = (4.5) / (2) = 2.25
If given that y=3, then:
3 = (4.5) / x
x = (4.5) / (3) = 1.5

Given:
Two brothers are sharing a certain sum of money in the ratio 
.
The largest share was Gh¢500.00.
To find:
The total amount shared between them.
Solution:
It is given that, two brothers are sharing a certain sum of money in the ratio .
First we need to make the denominators common.
So, the two brothers are sharing a certain sum of money in the ratio 10:9.
Let the shares of two brothers are 10x and 9x respectively. So, the larger share is 10x.
It is given that the largest share was Gh¢500.00.
Now, the total amount shared between them is:
Therefore, the total amount shared between them is Gh¢950.00.
