IRISSAK [1]2 years ago

Answer:

b=1

Step-by-step explanation:

\sf -11 + 3(b + 5) = 7

<u>First, let's regroup, terms,</u>

\sf 3(b+5)-11=7

<u>Add 11 to both sides,</u>

\sf 3(b+5)=7+11

<u>Simplify, 7+11 = 18,</u>

\sf 3(b+5)=18

<u>Now, divide both sides by 3,</u>

\sf b+5=\frac{18}{3}

<u>Simplify, 18/3 = 6,</u>

\sf b+5=6

Subtract 5 from both sides,

\sf b=6-5

\sf b=1

Hope it helps! :)
