Question

Solve for b: 2b+11=19​

Answer 1

Answer:

$b = 4$

Step-by-step explanation:

$2b + 11 = 19$

$2b + 11 - 11 = 19 - 11$

$2b = 8$

$\frac{2b}{2} = \frac{8}{2}$

$b = 4$

Answer 2

Answer:

$\Huge \boxed{B=4}$

Step-by-step explanation:

To solve this problem, first you have to isolate b on one side of the equation.

First, subtract 11 from both sides.

$\displaystyle 2b+11-11=19-11$

Solve.

$\displaystyle 19-11=\boxed{8}$

$\displaystyle 2b=8$

Then, divide by 2 from both sides.

$\displaystyle \frac{2b}{2}=\frac{8}{2}$

Solve.

$\displaystyle 8\div2=\boxed{4}$

$\large\boxed{\textnormal{Therefore, the correct answer is \boxed{b=4}}}}}.$
