Answer:
b=1
Step-by-step explanation:
![\sf -11 + 3(b + 5) = 7](https://tex.z-dn.net/?f=%5Csf%20-11%20%2B%203%28b%20%2B%205%29%20%3D%207)
<u>First, let's regroup, terms,</u>
![\sf 3(b+5)-11=7](https://tex.z-dn.net/?f=%5Csf%203%28b%2B5%29-11%3D7)
<u>Add 11 to both sides,</u>
![\sf 3(b+5)=7+11](https://tex.z-dn.net/?f=%5Csf%203%28b%2B5%29%3D7%2B11)
<u>Simplify, 7+11 = 18,</u>
![\sf 3(b+5)=18](https://tex.z-dn.net/?f=%5Csf%203%28b%2B5%29%3D18)
<u>Now, divide both sides by 3,</u>
![\sf b+5=\frac{18}{3}](https://tex.z-dn.net/?f=%5Csf%20b%2B5%3D%5Cfrac%7B18%7D%7B3%7D)
<u>Simplify, 18/3 = 6,</u>
![\sf b+5=6](https://tex.z-dn.net/?f=%5Csf%20b%2B5%3D6)
Subtract 5 from both sides,
![\sf b=6-5](https://tex.z-dn.net/?f=%5Csf%20b%3D6-5)
![\sf b=1](https://tex.z-dn.net/?f=%5Csf%20b%3D1)
Hope it helps! :)
