Answer:
B. 
Step-by-step explanation:
we know that
If a ordered pair is a solution of a linear equation. then the ordered pair must satisfy the linear equation
In this problem we have

<u>verify each case</u>
case A) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is not true
therefore
The ordered pair case A) is not a solution
case B) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is true
therefore
The ordered pair case B) is a solution
case C) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is not true
therefore
The ordered pair case C) is not a solution
case D) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is not true
therefore
The ordered pair case D) is not a solution
5+(1/7)b=-2
First subtract 5 from both sides. Our goal is to isolate b.
5+(1/7)b-5= -2-5
(1/7)b= -7
Now multiply both sides by 7 because (1/7)*7= 7/7 or 1.
7* (1/7)b= -7*7
1b= -49
Final answer: b= -49
Answer:
I'm just going to take a guess and say 36?
