Infinitely many because if you subtract 7x from both sides, you get 4 = 4, which is true at all times no matter what x is.
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 10

To determine the slope, you can use the following formula:
(y2-y1)/(x2-x1)
Answer:
∠ ABC = 116°
Step-by-step explanation:
Since the angles are supplementary, they sum to 180° , that is
8x - 36 + 4x - 12 = 180
12x - 48 = 180 ( add 48 to both sides )
12x = 228 ( divide both sides by 12 )
x = 19
Then
∠ ABC = 8x - 36 = 8(19) - 36 = 152 - 36 = 116°
