Hey there!
First, we will do the subtraction with the two like terms on the left. I know they're like terms because although they have different coefficients, they have the same variable.
We have:
2n=4
Divide both sides by 3 to get:
n = 2
Hope this helps!
        
                    
             
        
        
        
Step-by-step explanation:
3x - 2y = 12
Substituting y = 9, we find:

Similarly, solving for point B (4, __) =B (4, 0)
 
        
             
        
        
        
An expression is defined as a set of numbers, variables, and mathematical operations. The correct options are A and C.
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context. 
The given exponential (6⁻¹⁰/6⁻⁴) function can be simplified as shown below,
(6⁻¹⁰/6⁻⁴)
 = 6⁻¹⁰ × 6⁴
 = 6⁽⁻¹⁰⁺⁴⁾
 = 6⁻⁶
 = 1/6⁶
Hence, the correct options are A and C.
