Hey there! :D

y=2x-9

We can plug that in as y, since y is equal to 2x-9. 

5x-3(2x-9)= 23

Distribute. 

5x-6x+27= 23

-1x+27=23

Subtract 27 on both sides. 

-1x=-4

Divide both sides by -1.

x=4

Now, plug that in for y. 

y=2(4)-9

y=8-9

y=-1

 (4,-1) <== solution

I hope this helps!

Determine algebraically whether the function is even, odd, or neither even nor odd.
m_a_m_a [10]
For a function (fn) to be odd:
f(x) = - f(-x)
For a fn to be even:
f(x) = f(-x)
For a fn to be neither even nor odd
f(x) != f(-x)  [No Relation]

(-x)^n = x^n   for n -> even
(-x)^n = -x^n  for n -> odd
In your example:

f(x) = -4x^3 + 4x
f(-x) = -4 (-x)^3 + 4 (-x)^1  ( 3 and 1 are odd powers )
f(-x) = 4x^3 - 4x   (take -1 common to do the check)
f(-x) = -( -4x^3 + 4x ) = - f(x)  [between the bracket was the original fn]

f(x) = - f(-x)   
so the function is odd also called symmetric about the origin
