Answer 1

Answer:

5+2b=9

2b=9-5

b=4/2

b=2

Answer 2

Answer:

$\boxed{\sf{b=2}}$

Step-by-step explanation:

Isolate the b from one side of the equation.

First, subtract by 5 from both sides.

$\sf{5+2b-5=9-5}$

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

$\Longrightarrow \boxed{\sf{b=2}}$

Therefore, the correct answer is b=2.
