First isolate by subtracting 1 from both sides of the equation.
That gives you .
From here, since x is being divided by 2, multiply both sides of the equation by 2.
So <em>x = 10</em>.

His mean score for the first 4 games will be 18 points.
Explanation
In the first 3 games, the mean of the scores is 15 points . Mean is the simple average of some numbers.
So, the total score in first 3 games = points
Now, in the 4th game, he scored 27 points. So, the total score in the first 4 games = points
Thus, the average of scores in first 4 games = points
So, his mean score for the first 4 games will be 18 points.
The number of students is an illustration of a linear function
There are 1320 students in branch B
<h3>How to determine the number of students</h3>
From the question, we have the following equation that represents the number of students in branch A
A = 1650
Also, we have:
Multiply through by 4
Add 4B and B
Substitute 1650 for A
Divide through by 5
Hence, there are 1320 students in branch B
