Answer:
(6, -9)
Step-by-step explanation:
Our system of linear equations is:
6x + 2y = 18
-4x - 2y = -6
When we solve by elimination, we're essentially "eliminating" a variable so that we can solve for other more easily. Here, let's eliminate the y variable by adding the two equations together:
6x + 2y = 18
+ -4x - 2y = -6
____________
2x + 0y = 12
x = 12/2 = 6
Plug this back into one of the original equations to find y:
-4x - 2y = -6
-4 * 6 - 2y = -6
-24 - 2y = -6
-2y = 18
y = -9
The solution is (6, -9).
Answer:
Anish performed better than Aman.
Step-by-step explanation:
Given:
Marks obtained by Aman =410
Total marks = 500
We will first find the percentage of marks obtained.
To find the percentage of marks obtained we will divide Marks obtained by Total marks multiplied by 100.
framing in equation form we get;
Percentage of Aman =
Also Given:
Marks obtained by Anish = 536
Total marks = 600
We will first find the percentage of marks obtained.
To find the percentage of marks obtained we will divide Marks obtained by Total marks multiplied by 100.
framing in equation form we get;
Percentage of Anish =
Now we can see;
Percentage of Anish is greater than Percentage of Aman.
Hence Anish performed better than Aman.
