Question

What is -11 + 3(b + 5) = 7​

Answer 1

b=1

Explanation:

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

First, let's regroup, terms,

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

Add 11 to both sides,

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

Simplify, 7+11 = 18,

`\sf 3(b+5)=18`

Now, divide both sides by 3,

`\sf b+5=(18)/(3)`

Simplify, 18/3 = 6,

`\sf b+5=6`

Subtract 5 from both sides,

`\sf b=6-5`

`\sf b=1`

Hope it helps! :)
