Step-by-step explanation:
<h3>>> ▪︎ 3x-ax=2x+5 ▪︎<< </h3><h3>>> ▪︎ 3x-ax-2x=5 ▪︎<<</h3><h3>>> ▪︎x(3-2-a)=5 ▪︎<<</h3><h3>>> ▪︎x=5/1-a ▪︎<<</h3>
 
        
                    
             
        
        
        
B - the other base;
A = 9/2 ( b + 35 )   / * 2  ( we will multiply both sides of the equation by 2 )
2 A = 9 ( b + 35 )
b + 35 = 2 A / 9 
b + 35 - 35 = 2 A / 9 - 35
b = (2 A / 9 ) - 35
Answer: B ) b = 2 multiplied by A over 9 - 35
