Answer: x=1
Step-by-step explanation: 6x+24=30
6x=6
x=1
Answer:
5+9+-23
Step-by-step explanation:
The first x is the horizontal coodinate (abscisa) and second is the vertical coordinate (ordenate). Both are coordinates. (x,y) has the meaning of a complex number: x is the real part and y is the imaginary part: x+yi. (x,y) has the meaning of a plane's vector from origin of coordinates.
B. Y equals 0, because if you plug it in ( multiply 2 by 9 ) you will get 18-18 which equals 0.
Answer:

Step-by-step explanation:
We can write the following system of equations:

Adding both equations together, we isolate
and get:

Plugging
in any of the equations, we can solve for
:

Verify that the solution pair
works 
Therefore, the two numbers are
