Question

(iii) x + 21 = 20
please solve it...​

Answer 1

The given data in the above question,

It is given that the x+21=20

we have to find the value of x.

Thus, solving the given value we get,

$x+21=20$

shifting 21 from LHS to RHS we get

$x=20-21$

Substracting we get,

$x=-1$

Hence the value of x is -1.

Answer 2

In accordance with the information provided in the question,

We have find the value of the supplied expression in the above question.

Given the data in question  x + 21 = 20

Hence, for solving the above equation, we will solve it by separating the like terms at one side.

So, we will shift 21 from LHS to RHS,

So, we will get it as,

$=x+21=20\\=x=20-21\\x=-1$

Hence, value of "x" in above equation will be $-1$.
