Answer 2

It looks like you've provided a set of equations involving the variable "x." You're likely looking to solve for the value of "x" in each equation. Let's solve them one by one:

1. $4x = 4$ Divide both sides by 4: $x = 1$

2. $7x - 1 = 10$ Add 1 to both sides: $7x = 11$ Divide both sides by 7: $x = \frac{11}{7}$

3. $11x - 4 = 15 - x$ Add $x$ to both sides: $12x - 4 = 15$ Add 4 to both sides: $12x = 19$ Divide both sides by 12: $x = \frac{19}{12}$

4. $5(4x + 1) + 12 = 10x - 7$ Distribute 5 on the left side: $20x + 5 + 12 = 10x - 7$ Combine constants on the left side: $20x + 17 = 10x - 7$ Subtract $10x$ from both sides: $10x + 17 = -7$ Subtract 17 from both sides: $10x = -24$ Divide both sides by 10: $x = -\frac{24}{10}$ Simplify the fraction: $x = -\frac{12}{5}$

So, the solutions for each equation are:

1. $x = 1$
2. $x = \frac{11}{7}$
3. $x = \frac{19}{12}$
4. $x = -\frac{12}{5}$
