5x + 12 = x - 8
Let's get rid of that x on the right-hand side of the equation.
We can do this subtracting x from each side of the equation.
(5x - x) + 12 = (x - x) - 8 =
4x + 12 = -8
Let's take out the 12 so that the 4x can be alone.
We can do that by subtracting 12 from each side
4x + (12 - 12) = -8 - 12 =
4x = -20
And finally, divide the both sides by the coefficient of the 4x term. Which is 4.
4x / 4 = -20 / 4 =
x = -5
So, x is equal to -5.

Step-by-step explanation:
Probability is particular about a certain outcome of an event relative to the total possible outcome in the event.
Mathematically, Probability = favourable outcome/possible outcome.
In this case, favourable outcome = number of students from kenilworth 44 + 33 = 77
Possible outcome = total number of students = 111 + 44 + 99 + 77 + 33 + 77 = 441
Hence, probability of choosing a student from kenilworth = 77/441 = 0.175 (3d.p)
