What is the value of b if b + 10 / 2 = 9 when b = -2 and b = 8

To solve the equation ( b + frac{10}{2} = 9 ), we need to simplify and isolate ( b ).

1. First, simplify ( frac{10}{2} ) to get 5. So the equation becomes:

[

b + 5 = 9

]

2. Next, subtract 5 from both sides to isolate ( b ):

[

b = 9 – 5

]

3. Simplifying that gives:

[

b = 4

]

Therefore, neither ( b = -2 ) nor ( b = 8 ) is correct. The solution to the equation is ( b = 4 ). If you have more questions or need further assistance, feel free to ask!

To solve the equation ( b + frac{10}{2} = 9 ), first simplify the fraction:

1. Calculate ( frac{10}{2} ):

[

frac{10}{2} = 5

]

2. Now, rewrite the equation:

[

b + 5 = 9

]

3. To isolate ( b ), subtract 5 from both sides:

[

b = 9 – 5

]

[

b = 4

]

Therefore, the correct answer is ( b = 4 ). Neither ( -2 ) nor ( 8 ) is correct. If you have more questions or need further assistance, feel free to ask!
