Answer:

In this case, you can simply treat the > sign like an = sign. The only time you would need to worry about is when multiplying or dividing by negative numbers.

2x + 3 > 13

2x + 3 - 3 > 13 - 3

2x > 10

2x / 2 > 10 / 2

x > 5

Semenov [28]

Answer:

(x + 9)(x + 2 )

Step-by-step explanation:
