Question

5b-b-1 > or equal too-11

Answer 1

-2.5

Explanation:

5b - b - 1 ≥ -11

4b - 1 ≥ -11

+1 +1

4b ≥ -10

4/4 -10/4

b ≥ -2.5

Answer 2

b ≥
`-(5)/(2)`

Explanation:

The expression:

5b - b - 1 ≥ -11

Now to solve this problem, we must be aware of some rules of inequality.

When dividing or multiplying with a negative value, the sign of the inequality must change;

5b - b - 1 ≥ -11

4b - 1 ≥ -11

Add + 1 to both sides;

4b -1 + 1 ≥ -11 + 1

4b ≥ -10

Now divided both sides by 4;

`(4b)/(4)` ≥
`(-10)/(4)`

b ≥
`-(5)/(2)`
