Question

Solve for b: 2b+11=19​

Answer 1

`\Huge \boxed{B=4}`

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 (2b)/(2)=(8)/(2)`

Solve.

`\displaystyle 8/2=\boxed{4}`

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

Answer 2

`b = 4`

Explanation:

`2b + 11 = 19`

`2b + 11 - 11 = 19 - 11`

`2b = 8`

`(2b)/(2) = (8)/(2)`

`b = 4`
