Answer 1

To solve the given system of inequalities:

1. 25 - 6x < 4 + x

Let's simplify this inequality:

25 - 6x - x < 4

Combine like terms:

25 - 7x < 4

Subtract 25 from both sides:

-7x < 4 - 25

-7x < -21

To isolate x, divide both sides by -7, remembering to flip the inequality:

x > -21 / -7

x > 3

2. 3x + 7.7 > 1 + 4x

Let's simplify this inequality:

3x - 4x > 1 - 7.7

Combine like terms:

-x > -6.7

Divide both sides by -1, remembering to flip the inequality:

x < -6.7 / -1

x < 6.7

Therefore, the solution to the given system of inequalities is:

x > 3 and x < 6.7
