Question

decide whether given value our solution of equation or not

1. 2m+7=9


2. m= 1,-1,2
​

Answer 1

m = 1

is the correct value of m.

Answer 2

Answer:

2m + 7 = 9

put m = -1

2(-1)+7 = 9

-2=9-7

-2 = 2

0 = 4

no, -1 isn't the solution of the equation

now,

put m=1

2(1)+7 =9

2+7=9

9=9

0 = 9-9

0 = 0

yes, 1 is the solution of the equation

now, put m = 2

2(2)+7=9

4+7=9

11=9

0 = 9-11

0 = -4

no, 2 is not the solution of the equation
