Question

6.3-_________=2.1

please answer me now fastttttt....​

Answer 1

Given: $6.3-( - )=2.1$

We have to find the value in the dash place of the equation. i.e $6.3-( - )=2.1$

For this, we assume the value will be $x$in the dash place, and then we will simplify the equation.

We are solving in the following way:

We have

$6.3-( - )=2.1$

Now,

=> $6.3-( - )=2.1$

Let assume the value will be$x$.

$=>6.3-x=2.1$

$=>-x=2.1-6.3\\=>-x=-4.2\\=>x=4.2$

We get$x=4.2$

Hence, the value will be$4.2$. when we subtract this value from$6.3$ we get$2.1$.

Answer 2

To find : missing number .

Given : $6.3 - ? = 2.1$

Solution :

• Let , the missing number be $x$ .
• Then , we have ,$6.3 -x = 2.1$ .

• Taking variable to RHS and constants at LHS we find value of $x$.

                                   $6.3 - 2.1 = x$

                                               $x = 4.2$

Hence , missing number is $4.2$
