Question

How do you solve `68\geq 60- b`?

Answer 1

`color(blue)(b >= -8`

Explanation:

Given
`color(white)("XXX")68 >= 60-b`

Add `b` to both sides
`color(white)("XXX")68+b >= 60`

Subtract `68` from both sides
`color(white)("XXX")b >= -8`

Note: you can always add or subtract the same amount to both sides of an inequality without changing the direction or validity of the inequality.
