Question

Transposing method

+ 21 = 5
how to do ?​

Answer 1

`x + 21 = 5`

`x = 5 - 21`

`\color{hotpink}x = ( - 16)`

Let us check whether or not we have found out the correct value of x , by placing -16 in the place of x :-

`- 16 + 21 = 5`

`5=5`

`\color{hotpink}LHS = RHS`

As the left hand side of the equation is equivalent to the right hand side of the equation, we can conclude that we have found out the correct value of x .

Therefore , the value of :-

`\color{hotpink}x \color{olive}=\color{hotpink} ( - 16)`
