Answer 2

To solve the inequalities, let's go step by step:

1. 0.7x + 8 > 0.8 - 1

First, let's simplify the right side of the inequality: 0.8 - 1 = -0.2

Now we can rewrite the inequality: 0.7x + 8 > -0.2

Next, subtract 8 from both sides of the inequality: 0.7x > -0.2 - 8 0.7x > -8.2

To isolate x, divide both sides of the inequality by 0.7 (the coefficient of x): x > -8.2 / 0.7

The simplified solution is: x > -11.71

2. 3x - 4 > 6 - 2x

First, let's simplify both sides of the inequality: 3x - 4 > 6 - 2x Add 2x to both sides: 3x + 2x - 4 > 6 Combine like terms: 5x - 4 > 6

Next, add 4 to both sides of the inequality: 5x - 4 + 4 > 6 + 4 5x > 10

To isolate x, divide both sides of the inequality by 5: x > 10 / 5

The simplified solution is: x > 2

So the final solutions for the two inequalities are:

1. x > -11.71
2. x > 2
