Consider the following system of equations. 3x + 5y = 18
6x - 5y = 20
Decide which procedures eliminate the x variable and which eliminate the y variable.
Subtract the second equation from the first equation
Add the first and second equations.
Multiply the first equation by -2; then add the two equations.
Divide the second equation by -2; then add the two equations.
Subtract the first equation from the second equation
Multiply the first equation by 2 then add the two equations.

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)
