Given system of linear equations are ,
- x + y = 2
- -3x + y = 2
And we need to find the Solution of the linear equation . So let's Firstly number the equations .
<u>→</u><u> </u><u>Multipl</u><u>ying</u><u> </u><u>equⁿ</u><u> </u><u>(</u><u>i</u><u>)</u><u> </u><u>by</u><u> </u><u>3</u><u> </u><u>,</u>
=> 3 ( x + y ) = 2*3
=> 3x + 3y = 6
<u>→</u><u> </u><u>Addin</u><u>g</u><u> </u><u>the</u><u> </u><u>two</u><u> </u><u>equations </u><u>,</u><u> </u>
=> 3x + 3y -3y + y = 6 + 2
=> 4y = 8
=> y = 8/4
=> y = 2
<u>→</u><u> </u><u>Put</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>2</u><u> </u><u>in</u><u> </u><u>(</u><u>i</u><u>)</u><u> </u><u>,</u>
=> x + y = 2
=> x + 2 = 2
=> x = 2- 2
=> x = 0
<h3><u>★</u><u> </u><u>Hence</u><u> the required solution is ( 0 , 2 ) .</u></h3>Answer:
The required equation
C should be correct.
Step-by-step explanation:
Given: Julissa is running a 10-kilometer race at a constant pace.
After running for 18 minutes, she completes 2 kilometers.
First point: (18,2)
After running for 54 minutes, she completes 6 kilometers.
Second Point: (54,6)
We need to write an equation letting t, the time in minutes, represent the independent variable and k, the number of kilometers, represent the dependent variable
Using two point formula to find the equation of line
Formula:
Required Equation:
Hence, The required equation
