Question

Can you show me how to find the answer to -9+2a<3a= ?

Answer 1

a > -9

Explanation:

-9 + 2a < 3a

1. Add 9 to both sides

-9 + 2a + 9 < 3a + 9

2. Simplify

2a < 3a + 9

3. Subtract 3a from both sides

2a - 3a < 3a + 9 - 3a

4. Simplify

-a < 9

5. Multiply both sides by -1 (reverse the inequality)

(-a)(-1) > 9(-1)

6. Simplify

a > -9
