Hey there!
We can form this equation in slope-intercept form
This means, we have to find the slope and the y intercept of the line
First lets find the slope
The equation for slope is
In order to find y and x, we need to take two points on the line
(-4, 0) and (0, -3)
x1 y1 x2 y2
Plug it in:
This means, the slope is -3/4
Now we have to find the y-intercept
The y-intercept is where the line intercepts the y-axis
The line intercepts the y-axis at the point (0, -3)
So now that we have the slope and the y-intercept, we can form the equation

I'm thinking this is what the problem looks like: 
. The first thing to do is to move the 
over to the other side because it has a common denominator with the other side. Doing that and at the same time combining them over their common denominator looks like this: 
. The best way to solve for x now is to cross-multiply to get 3(4-x)=-4(x-4). Distributing through the parenthesis is 12 - 3x = -4x + 16. Solving for x gives us x = 4. Of course when we sub a 4 back in for x we get real problems, don't we? Dividing by zero breaks every rule in math that there ever was! So, yes, the solution is extraneous.
