Question

Check whether q=-1 is the solution of given equation 3q + 9 = 8. Please Answer With Explanation

Answer 1

Answer:

Step-by-step explanation:

by keeping the value of q = -1 in equation we get

3*(-1) + 9 = 8

-3 + 9 = 8

6 = 8

-  here 6 is not equal to 8

so the solution for q = -1 is wrong
