Answer 2

It looks like you've provided two linear inequalities:

1. $8x - 3 > 5x + 6$
2. $7y - 13 < 5y - 9$

To solve these inequalities, let's start by solving each one separately:

1. $8x - 3 > 5x + 6$

Subtract $5x$ from both sides: $8x - 5x - 3 > 6$

Simplify: $3x - 3 > 6$

Add 3 to both sides: $3x > 9$

Divide by 3: $x > 3$

So, the solution to the first inequality is $x > 3$.

2. $7y - 13 < 5y - 9$

Subtract $5y$ from both sides: $7y - 5y - 13 < -9$

Simplify: $2y - 13 < -9$

Add 13 to both sides: $2y < 4$

Divide by 2: $y < 2$

The solution to the second inequality is $y < 2$.

To summarize:

1. The solution to $8x - 3 > 5x + 6$ is $x > 3$.
2. The solution to $7y - 13 < 5y - 9$ is $y < 2$.
