Hey !
Question :
For each value of x determine whether it is a solution to 45 = -9 ( x + 5 )
Given :
In the question we have given an equation i.e. :
In the question values of x are also given i.e. :
To Determine :
In this question we have to determine whether given value of x are solution fo the given equation or not .
How we have to solve this question :
We are solving this question by substituting given value of x in the equation if equation satisfied then it means that the value for x is solution of the equation .
So Let's get started :
1) Value of x as 5 :
- 45 = -9 ( x + 5 ) ( Given Equation )
Now substituting value of x as 5 :
- 45 = -9 ( 5 + 5 )
- 45 = -9 ( 10 )
- 45 = -90
- But , 45 is not equal to -90
Therefore , 5 is not the solution for equation .
2) Value of x as -7 :
- 45 = -9 ( x + 5 ) ( Given Equation )
Now substituting value of x as -7 :
- 45 = -9 ( -7 + 5 )
- 45 = -9 ( -2 )
- 45 = 18
- But , 45 is not equal to 18
Therefore , -7 is not the solution for equation .
3) Value of x as 1 :
- 45 = -9 ( x + 5 ) ( Given Equation )
Now substituting value of x as 1 :
- 45 = -9 ( 1 + 5 )
- 45 = -9 ( 6 )
- 45 = -54
- But , 45 is not equal to -54
Therefore , 1 is not the solution for equation .
4) Value of x as -4 :
- 45 = -9 ( x + 5 ) ( Given Equation )
Now substituting value of x as -4 :
- 45 = -9 ( -4 + 5 )
- 45 = -9 ( 1 )
- 45 = -9
- But , 45 is not equal to -9
Therefore , -4 is not the solution for equation .
So ,
- In there is no proper value of x that can be solution of the given equation .
