Question

Decide whether all values given are the solution of equation or not ?

X -4 = 3 where x = -1,7,-7​

Answer 1

Given: x-4 = 3

To find: value of x

Step-by-step explanation:

x-4 = 3

⇒ For x = -1

    x-4 = 3

   -1 - 4 = 3

    -5 ≠ 3

⇒ For x = 7

   x - 4 = 3

   7-4 = 3

    3 = 3

⇒ For x = -7

    x - 4 = 3

    -7-3 = 3

     -10 ≠ 3

Answer: value of x for given equation is 7.
