Question

check weather x = 3 would be a solution of 2 X - 1 = 7 or not.​

Answer 1

Question -:

Check whether x = 3 would be a solution of 2x - 1 = 7 or not.

$\huge\orange{\underline{\overline{\tt\: Answer}}\mid}$

Putting 3 in place of x, we get -:

3x - 1 = 7 as 3 × 3 - 1 = 7.

3 × 3 - 1 = 7

9 - 1 = 7

8 = 7.

Since 8 is not equal to 7, therefore x = 3 is not a solution of the above equation.

Hope it helps! :)

Answer 2

Answer:

No, x is not equal to 3

Step-by-step explanation:

Lets substitute x=3

2×3-1=7

6-1=7

5≠7

Hence x is not equal to 3
