<span>5-6n=2n+5 , 5 cancels out
-6n -2n = 0
-8n = 0
n =0</span>
Proabably. 5 because if there is 2 sides on a coin then you should divide 10÷2 which is 5.
A linear equation that represents the model is: x + 6 = 10; x = 4
<h3>How to solve linear equations?</h3>
Let us first define the variables based on the attached image of the ball balance:
Let x = number of balls that contains the square.
On the left side, we have; square + 6 balls
On the right side, we have; 10 balls
To balance this, we have;
x + 6 = 10
x = 10-6
x = 4
Thus, a linear equation that represents the model is:
x + 6 = 10; x = 4
