Here,
D=[2132]=4(3)=7
Dx=[10112]=201=21
Dy=[21031]=2(30)=28
By using cramer's rule
x=DxD=(21)7=3
y=DyD=287=4
Thus,
x=-3
y=4

If a system of linear equations can be represented by the compact form,
Ax=b
how will a system of nonlinear equations (system of quadratic equations and system of exponential equations) be represented in compact form?

Can someone give an intuition of how linear equations in two variable are mapped to a 2-D plots in the forms of lines ? And why are the axes perpendicular ?
I mean how come someone come with the idea of plotting the equations as line? Axes?

Consider a simple linear equation of the form:
n=2x+23
Let n and x represent something that comes in whole positive quantities (for example physical objects).
How can I
1.Define the equation only for n and x that are a part of natural numbers (whole numbers >0)
2.Solve the equation satisfying the above restriction (without for instace graphing it and looking for n and x that work)
Thanks!

Can anybody tell me where can I find some REAL problems (i.e. form real life) that can be solved using a 3 × 3 system of linear equations? Or, can anybody give me an example? A solution could be a circuit in electrical engineering, but this is not very interesting, and it doesn't seem to be so real. Thanks.

If we want to graph a horizontal line, we will do the following:
y=0x+3
No matter the domain for x, the range for y will always be 3. Therefore, we have a horizontal line.
y=0(0)+3=(0,3)
y=0(1)+3=(1,3)
y=0(2)+3=(2,3)
Now the formula to graph a vertical line looks like this:
x=3
Well, wait a second. Where is the y? I would like to see the y in the equation. But it is missing. How can I write the equation for a vertical line that includes the y variable? This is all I can think of:
x=0y+3
And with the following domain:
x=0(0)+3
x=0(1)+3
x=0(2)+3Is this correct? Is it ok to reverse the x and y, as I just did above? Or does this not make it a slope-intercept equation anymore? It should still be a linear equation, since the variables are raised to the first power, in my opinion. But the slope-intercept form looks like this: y = mx + b. So I am not sure if this is still a slope-intercept equation.
