Question

-9 < 8(r - 17) - 1
Solve for r

Answer 1

r>16

Explanation:

1.) Add 11 to both sides.

-9+1<8(r-17)−9+1<8(r−17)

2.) Simplify -9+1−9+1 to -8−8.

-8<8(r-17)−8<8(r−17)

3.) Divide both sides by 88.

-1<r-17−1<r−17

4.) Add 1717 to both sides.

-1+17<r−1+17<r

5.) Simplify -1+17−1+17 to 16.

16<r16<r

6.) Switch sides.

r>16r
