Question

How do you solve the inequality `2 + 7 ≤ 17 + 2y` or `4y ≥ 49 - 3y`?

Answer 1

`y>=7`

Explanation:

`9<=17+2y`
Get`y>=-4`
`4y>=49-3y`
Get `y>=7`
Combine 2 results `=>y>=7`
This solution both satisfies these inequalities.
Why don't choose `y>=-4`?
Because if you let `y=-1` bring in the second inequality
It doesn't correspond.
