Question

Solve for b.

4(b + 8) + 11 = 19

Answer 1

Answer:

$4(b + 8) + 11 = 19\\ 4b + 32 + 11 = 19 \\ 4b + 43 = 19 \\ 4b = 19 - 43 \\ 4b = - 24 \\ b = - \frac { 24}{4} \\ = > - 6$

Answer 2

Here is ur a answer -

• firstly, opening brackets we would get -

$4(b + 8) + 11 = 19 \\ \\ 4 \times b + 4 \times 8 + 11 = 19\\ \\ 4b + 32 + 11 = 19$

• transposing terms to RHS, for the value of "b" we get -

$4b + 32 + 11 = 19 \\ \\ 4b + 43 = 19 \\ \\ 4b = 19 - 43 \\ \\ 4b = - 24 \\ \\ b = \frac{ - 24}{4} \\ \\ b = - 6$

→ b = -6⠀⠀⠀⠀⠀⠀

Hence, by computing 4(b+8) + 11=19 we get value of b = 6
