Question

what is the answer ? ​

Answer 1

Answer:

here we have given x=2

so in the place of x we will put 2

2(2)+7=9

4+7=11

by placing 2 in place of x we get 11 not 9 so it is not a solution

Answer 2

Answer:

the variable in the bracket is not a solution to the equation

Step-by-step explanation:

2x + 7 = 9

2x = 9 - 7

2x = 2

x = 1
