Question

(4(x - 2))/5 - (7(x - 4))/6 = (x - 5)/4 + 37/60 find the value of x

Answer 1

Answer:

Your Answer :

Step-by-step explanation:

We have,  

7x−4y=49...(i)  and  

5x−6y=57...(ii)

Here  

a

​

=7,b

​

=−4,c  

1

​

=49  and  

a

​

=5,b

​

=−6,c

​

=57

So,  

a

b

​

 

b

​

 

​

=

−4

​

=

Since,  

a

​

 

a

​

 

​

 



=  

b  

2

​

 

b  

1

​

 

​

 

The system has a unique solution.

Now, Multiply equation (i) by 5 and equation (ii) by 7 and subtract,

  35x−20y=245

  35x−42y=399

   

22y=−154

​

 

⇒y=−7

Put y=−7 in equation (ii)  

5x−6(−7)=57

⇒5x=57−42

⇒x=3

Hence x=3 and y=−7
