Answer

2x-3=7 

Take 3 right side and change its sign

2x=7+3

2x=10

Here 2 is multiplying, take 2 right side it will devide with 10.

X= 10/. 2

X=5

 

 

Answer

2x-3 =7 

Adding 3 to both sides,we get, 

2x -3 +3 =7 +3

Cancelling -3 & +3 on the left hand side 2x =10,

Dividing both sides by 2,we get 2x/2 =10/2 

Now,x= 5  Ans.

Answer

2x - 3 = 7

=> 2x = 7 +3

=> 2x = 10

=> x = 10/2

=> x =5
