Answer:
Multiply the top equation by -3 and the bottom equation by 2
Step-by-step explanation:
Given <u>system of equations</u>:
To solve the given system of equations by addition, make one of the variables in both equations <u>sum to zero</u>. To do this, the chosen variable must have the <u>same coefficient</u>, but it should be <u>negative</u> in one equation and <u>positive</u> in the other, so that when the two equations are added together, the variable is <u>eliminated</u>.
<u>To eliminate the </u><u>variable y</u>:
Multiply the top equation by -3 to make the coefficient of the y variable 6:
Multiply the bottom equation by 2 to make the coefficient of the y variable -6:
Add the two equations together to <u>eliminate y</u>:
<u>Solve</u> for x:
<u>Substitute</u> the found value of x into one of the equations and <u>solve for y</u>:

Answer: ( 11, -2 )
Step-by-step explanation:
The mid point of a line is calculated using the formula:
M = ( ,
)
From the question , the mid point is already given , substituting , we have :
(5 , - 7.5 ) = ( ,
)
Equating the x component to x and the y component to y , we have
5 =
x - 1 = 10
x = 11
Also
- 7.5 =
-15 = y - 13
-15 + 13 = y
Therefore : y = -2
Therefore : the location of point P is ( 11, -2 )
