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.

Step-by-step explanation:

X = 4 – 1 = 3
Y = 4 – 2 = 2

Equation of the line:
y = 0.66666666666667x + 1.3333333333333
or

When x=0, y = 1.3333333333333
When y=0, x = -2
