5x-4-x=4(x+1)
5x-4-x=4(x)+4(1)
(5x-x)-4=4x+4
4x-4=4x+4
+4 +4
4x=4x+8
/4 /4
x = x+2
-x -x
0=2
Answer:

Step-by-step explanation:
First let's write our equation

Now let's make them improper fractions

Now since we're dividing we with fractions we do the reciprocal and multiply

or

10.39 is the measure of angle C.
To find slope it is rise over run which is 20/60 but that can be reduced to 1/3. Do your equation of the line is y=1/3x
