Question

Solve the following equations.
X-2=7​

Answer 1

Answer:

X-2=7

X=7+2

X=9

value of X is 9

Answer 2

X - 2 = 7, SO Here it is showing that the difference of two numbers is 7. The second number is 2. We have to find out the first number which is now know as X.  Here, we are doing subtraction.

So just do addition = difference of two numbers + Second number

                                 = first number.

So, 7 + 2 = 9.                  

Now you check that what will come if we subtract 2 from 9.
