Answer:
[tex]\boxed{\sf{b=2}}[/tex]
Step-by-step explanation:
Isolate the b from one side of the equation.
First, subtract by 5 from both sides.
[tex]\sf{5+2b-5=9-5}[/tex]
Solve.
Subtract.
9-5=4
2b=4
Divide by 2 from both sides.
2b/2=4/2
Solve.
Divide the numbers from left to right.
4/2=2
[tex]\Longrightarrow \boxed{\sf{b=2}}[/tex]
Therefore, the correct answer is b=2.
