Answer: {(5,0), (3,4)}
Step-by-step explanation:
You can apply the Substitution method:
- Solve for y from the second equation.
- Substitute into the first equation and solve for x.
Then:


(Remember that:
)

Substitute the values obtained into one of the original equation and solve for y:

The solution set is: {(5,0), (3,4)}
6,5 is two points to this equation
We have been that Arelli drank 2/3 liter of water Monday before going jogging. She drank 5/7 liter of water after her jog. We are asked to find the amount of water that Arelli drink altogether.
To find the amount of water that Arelli drink altogether, we will add amounts of water drank before going to jogging and after the jogging.

Let us make a common denominator.


Now we will combine numerators.



Therefore, Arelli drank
liters of water altogether.
Remove parentheses.
-3/8 -1/6
Find the Least Common Denominator (LCD) of 3/8, 1/6. In other words, find the Least Common Multiple (LCM) of 8,6.
LCD=24
Make the denominators the same as the LCD.
- 3x3/8x3 - 1x4/6x4
Simplify. Denominators are now the same
-9/24 - 4/24
Join the denominators
-9-4/24
Simplify
-13/24
